Why is only one of these almost identical HTML-forms reacting to submit button click? - laravel

Question

I have two almost identical forms. One is meant to edit an item, and the other is meant to create an item. For some reason, the create-form does not react at all to submit button clicks, while the edit/update form works exactly as expected. I can not find any differences between the two that should result in this behavior.
I am as sure as I can be that this has nothing to do with back end. I have monitored network activity, ant the submit button for the create-form does not activate any kind of network activity at all.
Working update form:
#extends ('layout')
#section('middle-content')
<div class="wrapper">
<div id="page" class="container">
<h4>Edit Competition Category</h4>
<form method="POST" action="/competition-categories/{{$competitionCategory->id}}">
#csrf
#method('PUT')
<div class="form-group row">
<label for="competition-category-name-input" class="col-4 col-form-label">Name</label>
<div class="col-8">
<input id="competition-category-name-input" name="name" type="text" class="form-control" required="required" value="{{ $competitionCategory->name }}">
</div>
</div>
<div class="form-group row">
<label for="competition-category-abbreviation-input" class="col-4 col-form-label">Abbreviation</label>
<div class="col-8">
<input id="competition-category-abbreviation-input" name="abbreviation" type="text" class="form-control" required="required" value="{{ $competitionCategory->abbreviation }}">
</div>
</div>
<div class="form-group row">
<div class="offset-4 col-8">
<button name="submit" type="submit" class="btn btn-primary">Submit</button>
</div>
</div>
</form>
</div>
</div>
#endsection

This line: <form method="POST" action="/competition-categories"></form>
of your non working form, please remove </form> you started and closed it that's why.
