Description:

I have a list() field to edit a 1-dimensional array of strings as described here: https://laravel-admin.org/docs/en/model-form-json-fields#One-dimensional%20array I fill it with some entries and save. Then I want to remove the items, but they stay and won't go away. I see in the network monitor of my browser that the field is not included in the request at all, and I guess that's why the (empty) content of the field is not being handled in the first place to remove the saved entries.

Steps To Reproduce:

1. Add list() field to $form: $form->list('sources')->max(10)->min(0);
2. Add an item and save.
3. Make sure the item has been saved.
4. Edit again and remove item.
5. Item is still there, no changes.
