First link in the foreach row doesn't work

Hi everyone,

I have a bit of a weird bug in my code, and I can't put my finger on it exactly what the problem is. The first in the row does not respond to a link. The second and subsequent is no problem, only the first one.

Does anyone have an idea where to look for this?

Thank you in advance

<table class="table table-sm table-striped table-hover">
    <thead>
    <tr>
        <th scope="col">#</th>
        <th scope="col">user #</th>
        <th scope="col">Name</th>
        <th class="actions">Checkin</th>
    </tr>
    </thead>
    <tbody>@foreach($children as $child)
        <tr>
            <th scope="row">{{ $child->id}}</th>
            <td>{{ $child->user->fullname()}}</td>
            <td>{{ $child->fullName()}}</td>
            <td>
                <form action="{{ route('admin.checkins.manualcheckin') }}" id="checkin{{$child->id}}" method="GET">
                    @csrf
                    <input type="hidden" id="barcode" name="barcode" value="{{ $child->barcode }}">
                    <input type="image" name="submit" form="checkin{{$child->id}}" onclick="return confirm('manual check-in?')" src="{{ URL::to('/') }}/images/iconic_svg/account-login.svg" style="width: 20px;" />
                </form>
            </td>
        </tr>
    @endforeach
</tbody>
