Steps to recreate

Must be using MySQL 8.0 or greater due to nullable json column.

1. Clone this repo
2. composer install
3. Clone .env.example, set up your database creds
4. php artisan migrate
5. php artisan make:filament-user
6. Login at /admin/login
7. Go to Post resource
8. Create a post with all fields filled in - Title, Body, Category, Author
9. Check database has all these fields
10. Go to App\Filament\Resources\PostResource
11. Remove select options so you are left with:

Forms\Components\Select::make('category')
->options([]),

and

Forms\Components\Select::make('author')
->options([]),

12. Now go back to the post you created at /admin/posts/1/edit
13. Check no options exist in either select
14. Save resource
15. See that the database values have not changed for category and the author json.

This is not expected behaviour. If values no longer exist this should save the fields as null, just as when a user selects the placeholder manually.
