I am building a small web application where I am using Identity for Authentication and Authorization of users of my website. The problem I am currently facing is that when I go to Register page (make a GET request), values for Email and Password are already filled (which is already very weird). First of all I have no idea from where those values are coming from and secondly I have tried to use ModelState.Clear() in the OnGetAsync(). But it still does not works. Every time I load the page out of all the form fields Email and Password are prefilled. I would add some screenshots so you guys could see whats going on.
Here is Input model in my Register.cshtml.cs which is used in my Register.cshtml
public class InputModel
        {
            [MaxLength(15)]
            [Display(Name = "First Name")]
            public string FirstName { get; set; }
            [Display(Name = "Last Name")]
            [MaxLength(15)]
            public string LastName { get; set; }
            [Required]
            public string City { get; set; }
            [Required]
            public string State { get; set; }
            [Required]
            public string PhoneNumber { get; set; }
            [Required]
            [EmailAddress]
            [Display(Name = "Email")]
            public string Email { get; set; }
            [Required]
            [StringLength(100, ErrorMessage = "The {0} must be at least {2} and at max {1} characters long.", MinimumLength = 6)]
            [DataType(DataType.Password)]
            [Display(Name = "Password")]
            public string Password { get; set; }
            [DataType(DataType.Password)]
            [Display(Name = "Confirm password")]
            [Compare("Password", ErrorMessage = "The password and confirmation password do not match.")]
            public string ConfirmPassword { get; set; }
        }
Below is the OnGetAsync() in Register.cshtml.cs
public async Task OnGetAsync(string returnUrl = null)
        {
            ReturnUrl = returnUrl;
            ExternalLogins = (await _signInManager.GetExternalAuthenticationSchemesAsync()).ToList();
            ModelState.Clear();
        }
Below is Register.cshtml
@page
@model RegisterModel
@{
    ViewData["Title"] = "Register";
}
<h1>@ViewData["Title"]</h1>
<div class="row">
    <div class="col-md-4">
        <form asp-route-returnUrl="@Model.ReturnUrl" method="post">
            <h4>Create a new account.</h4>
            <hr />
            <div asp-validation-summary="All" class="text-danger"></div>
            <div class="form-group">

            <div class="form-group">

                <span class="text-danger" asp-validation-for="Input.City"></span>
            </div>
            <div class="form-group">

                <span class="text-danger" asp-validation-for="Input.State"></span>

            <div class="form-group">
                <label asp-for="Input.PhoneNumber"></label>
                <input class="form-control" type="text" asp-for="Input.PhoneNumber" />
                <span class="text-danger" asp-validation-for="Input.PhoneNumber"></span>
            </div>
            <div class="form-group">

                <input asp-for="Input.Email" class="form-control" />
                <span asp-validation-for="Input.Email" class="text-danger"></span>
            </div>
            <div class="form-group">
                <label asp-for="Input.Password"></label>
                <input asp-for="Input.Password" class="form-control" />
                <span asp-validation-for="Input.Password" class="text-danger"></span>
            </div>
            <div class="form-group">
                <label asp-for="Input.ConfirmPassword"></label>
                <input asp-for="Input.ConfirmPassword" class="form-control" />
                <span asp-validation-for="Input.ConfirmPassword" class="text-danger"></span>
            </div>
            <button type="submit" class="btn btn-primary">Register</button>
            <p>Already have an account? Click <a asp-page="Login" asp-area="Identity">Here</a> to login</p>
        </form>
    </div>
</div>
@section Scripts {
    <partial name="_ValidationScriptsPartial" />
}
EDIT
When I delete the Email and Password div(s) from the Register.cshtml page, the values are then displayed into PhoneNumber and ConfirmPassword input tags.
