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 and in a select input, I specified to only bring zero_ones that are not yet related to a 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 does not appear, only the 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()
              ->maxLength(255),
          ]),
        // Another attempt that didn't work:
        // Section::make('Zero One')
        //   ->headerActions([])
        //   ->relationship('zeroOne')
        //   ->schema([
        //     Forms\Components\TextInput::make('data')
        //       ->required()
        //       ->maxLength(255),
        //   ])
      ]);
  }
  // ...
}

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()
              ->maxLength(255),
          ]),
        // Another attempt that didn't work:
        // Section::make('Zero One')
        //   ->headerActions([])
        //   ->relationship('zeroOne')
        //   ->schema([
        //     Forms\Components\TextInput::make('data')
        //       ->required()
        //       ->maxLength(255),
        //   ])
      ]);
  }
  // ...
}

Tables: zero_ones(id, data) tests(id, zero_one_id [fk, nullable, unique, on delete set null], data) Models:

class Test extends Model {
  // ...
  public function zeroOne(): BelongsTo {
    return $this->belongsTo(ZeroOne::class);
  }
}
class ZeroOne extends Model {
  // ...
  public function test(): HasOne {
    return $this->hasOne(Test::class);
  }
}

class Test extends Model {
  // ...
  public function zeroOne(): BelongsTo {
    return $this->belongsTo(ZeroOne::class);
  }
}
class ZeroOne extends Model {
  // ...
  public function test(): HasOne {
    return $this->hasOne(Test::class);
  }
}

I think you need to add this modifyQueryUsing only in the create page https://discord.com/channels/883083792112300104/1263858697151447121/1263869505356959775

I found out I can use $record to access the current resource and successfully updated the query. I'm really sorry for the trouble and thank you so much for your help.
