->getStateUsing in v3 but ->state ist in de API doc so we changed it. Under the hood it is the same so it doesnt matter anyways.make does not exist - so name does not exists on the Record. It always has beed calculated on the flydump and noticed it is only executed in the first row - so I think the value is chached somehow. Could't find anything in the docs https://filamentphp.com/docs/4.x/tables/columns/overview#setting-the-state-of-a-column->formatStateUsing but this method is not executed if the value of make - so the property - does not exist.
