Missing field on relationship

I have this relationship fieldset
                Fieldset::make('Address')
                    ->relationship('address')
                    ->schema([
                        Forms\Components\TextInput::make('city')
                            ->required(),
                        Forms\Components\TextInput::make('state')
                            ->required(),
                        Forms\Components\TextInput::make('zip')
                            ->required(),
                        Forms\Components\TextInput::make('origin_country')
                            ->disabled()
                            ->dehydrated(false)
                            ->readOnly(),
                    ])
                    ->mutateRelationshipDataBeforeFillUsing(fn ($data) => dd($data)),


My issue is, in the $data, origin_country does not exist. But in the database it exists, in my model fillable it exists.

Am I missing something?
