Laravel collection stays empty on edit

Hello i have to simulair edit functions in laravel

public function edit(FieldOfStudy $fieldOfStudy)
    {
        return view(self::VIEW_FOLDER . 'edit', [
            'item' => $fieldOfStudy,
        ]);
    }

and

 public function edit(Exercise $exercise)
    {
        return view(self::VIEW_FOLDER . 'edit', [
            'item' => $exercise,
            'talents' => Talent::orderBy('name')->pluck('id', 'name')->all(),
        ]);
    }

the first one returns no data but the second one does

    }

the routes are als both recources

Route::resource('fieldofstudies', 'AdminFieldOfStudiesController')->except('show');
Route::resource('exercises', 'AdminExercisesController')->except('show');

Why is one empty and one full? If you need more data let me know. Thanks in advance. Both off the routes have data in the database with the id Laravel 8.
