Laravels foreach output is not complete

I wrote an eloquent statement in my model that outputs a whole lot of data which is fully modelled for my output. It returns the right content when i dump it in the backend (if you look at the comment below).

But whe i try to get it formatted with blade for my table, it cuts a whole lot of data at the top. It starts somewhere at the mid of all.

I tried a lot of styling like put some standard css from bootstrap and nothing at all, becaus i thought that this is an display error but it seems not like that.

Its a simple route:

Route::get('/', function () {
    $hs = App\Wl_steige::all()->first();
    $hs = $hs->getByStation('ptMetro')->groupBy('BEZEICHNUNG');
    //dump($hs = $hs->getByStation('ptMetro')->groupBy('BEZEICHNUNG'))
    return view('welcome', ['stellen' => collect($hs)]);
});

Thats the View:

<div class="card">
    <div class="card-body">
        <table class="table table-dark">
            <tbody>
                @foreach($stellen AS $line => $stations)
                <tr>
                    <th>Linie </th>
                </tr>
                @foreach($stations AS $station)
                <tr>
                    <td></td>
                    <td></td>
                    <td></td>
                    <td></td>
                    <td></td>
                </tr>
                @endforeach
                @endforeach
            </tbody>
        </table>
    </div>
</div>

I expected that it would begin at the top and not somewhere in the middle
