I'm trying to use the new behavior of Maui Community Toolkit, LongPress. When I press a line in the colectionview the data returned isn't the correct one. I show here my page

This is the viewmodel function called
public async void LongPress(EncomendaDetalhes encDet){ var resposta = await Application.Current.MainPage.DisplayAlert("Apagar IMEI ", encDet.IMEI, "Sim", "Não"); if (resposta) { await _encomendaservice.DeleteEncomendaDetalhes(encDet); Codigos.Remove(encDet); int iTmp = int.Parse(Lidos) - 1; Lidos = iTmp.ToString(); }}For instance
As you can see the data returned is not the one I pressed.
The viewmodel function just removes the item from CollectionView and database. I don't know how to reference the right viewmodel.
