Filter in table with a polymorphic Column

I would like to have a filter in a polymorphic model column, however it doesn't work. I don't know why.

The code:
->filters([
                Tables\Filters\SelectFilter::make('specifiable_type')
                    ->label('Type')
                    ->options(['App\Models\SpecChoice', 'App\Models\SpecNumber'])
            ])


The table works, however when I apply the filter no row appear. What is the problem?
