TitleAttribute doesn't appear in Form Select

What I am trying to do:
I am trying to model an optional one-to-one relationship.

What I did:
I created a resource for

Test

Test

Test

Test and in a select input, I specified to only bring

zero_ones

zero_ones

zero_ones

zero_ones that are not yet related to a

test

test

test

test.

My issue:
When searching and relating it for the first time, it works, but when I go to edit an already related one, the

titleAttribute

titleAttribute

titleAttribute

titleAttribute does not appear, only the

id

id

id

id does. I assume this is because it's not fetching the current or the same one. How can I retrieve the title of the currently selected one, or how should I handle this? Thank you in advance.

Code:

class TestResource extends Resource
{
  public static function form(Form $form): Form
  {
    return $form
      ->schema([
        Forms\Components\TextInput::make('data')
          ->required()
          ->maxLength(255),
        Forms\Components\Select::make('zero_one_id')
          ->relationship( // optional
            name: 'zeroOne', titleAttribute: 'data',
            modifyQueryUsing: fn(Builder $query)
              => $query->doesntHave('test'),
          )
          ->searchable()
          ->createOptionForm([
            Forms\Components\TextInput::make('data')
              ->required()
