I am using the following UpdateView in order to alter some values in the database:
class MyUpdateView(UpdateView):
    model = MyModel
    fields = ['VideoURL', 'MainDescription']
    template_name = 'myapp/edit.html'
This is my template:
    <div class="row">
        <div class="col-12 col-lg-7">
            <form method='post' class="card shadow-soft border p-4 mb-4">
                {% csrf_token %}
                <h5 class="mb-4">General</h5>
                <div class="form-group">
                    <label for="MainDescription">Title</label>
                    {{form.MainDescription|add_class:"form-control shadow-soft"}}
                </div>
                <div class="row">
                    <div class="col">
                        <button class="btn btn-primary btn-dark mt-2 animate-up-2"
                            type="submit">Update</button>
                    </div>
                </div>
            </form>
        </div>
        <div class="col-12 col-lg-5">
            <form method='post' class="card shadow-soft border p-4 mb-4">
                {% csrf_token %}
                <div class="form-group">
                    <label for="VideoURL">Video URL:</label>
                    {{form.VideoURL|add_class:"form-control shadow-soft"}}
                </div>
                <div class="row">
                    <div class="col">
                        <button class="btn btn-primary btn-dark mt-2 animate-up-2 text-right"
                            type="submit">Update</button>
                    </div>
                </div>
            </form>
        </div>
    </div>
However, I am facing some difficulties doing so because although both fields belongs to the same model, I cannot update any of the information. What I have noticed though is that if I place the both fields under the same HTML form, it works:
<div class="col-12 col-lg-5">
    <form method='post' class="card shadow-soft border p-4 mb-4">
        {% csrf_token %}
        <div class="form-group">
            <label for="VideoURL">Video URL:</label>
            {{form.VideoURL|add_class:"form-control shadow-soft"}}
        </div>
        <div class="form-group">
            <label for="MainDescription">Main Description:</label>
            {{form.MainDescription|add_class:"form-control shadow-soft"}}
        </div>
        <div class="row">
            <div class="col">
                <button class="btn btn-primary btn-dark mt-2 animate-up-2 text-right"
                    type="submit">Update</button>
            </div>
        </div>
    </form>
</div>
What am I missing here? Can anyone give me a hint? Thanks
Edit
It's due to how the forms are being displayed in the HTML form. They should be independent:
