MorphOne mutateRelationshipDataBeforeCreateUsing does not work properly

                Forms\Components\Section::make()
                    ->relationship('qrToken')
                    ->schema([
                        Forms\Components\TextInput::make('token'),
                    ])
                    ->mutateRelationshipDataBeforeCreateUsing(function (array $data) {
                        $data['token'] = QRCodeService::generateQRCodeToken();

                        return $data;
                    })
                    ->mutateRelationshipDataBeforeSaveUsing(function (array $data) {
                        dd($data); // --> Outputs the value inputted by the user NOT the mutated one.
                    return $data;
                }),
