Multiple definitions

[NebojsaMancic]

Describe the bug

I have installed nuget package and added [ObservableObject] to my ViewModel class. When I have build app, I have a lot of error messages for duplicated items

My ViewModel class looks like this

[ObservableObject]
public partial class KalkulacijaViewModel 
{

    [ObservableProperty]
    private int velicinaFonta;
    public KalkulacijaViewModel()
    {
    }

}

and errors are
