Disable SelectedDate in Calendar after reusing the control

[denmusic1992]

Greetings!
I have a Calendar control, which I use in such a way:

...
<calendar:Calendar BorderColor="Accent" BorderWidth="2" SelectedBackgroundColor="Accent" x:Name="MyCalendar"
                             SelectedTextColor="White" SelectedBorderWidth="0" TitleLeftArrowTextColor="Accent" StartDay="Monday" WeekdaysShow="False"
                             TitleRightArrowTextColor="Accent" EnableTitleMonthYearView="True" DateCommand="{Binding DateChanged}" Margin="5" 
                             SelectedDate="{Binding SelectedDate}"/>
...

And in my ViewModel:

public class DateDefectContentViewModel : BaseViewModel
{
    ...
    private DateTime? _selectedDate;
    public DateTime? SelectedDate
    {
	 get => _selectedDate;
	 set => SetProperty(ref _selectedDate, value);
    }
...

public DateDefectContentViewModel(CreateDefectModel defectModel)
{
	_defectModel = defectModel;
	SelectedDate = null;
	DateChanged = new DateSelectedCommand(this);
}

protected internal void SelectedDateChanged(object date)
{
	if (_defectModel.CreationDate == Convert.ToDateTime(date))
	{
		_defectModel.CreationDate = null;
		SelectedDate = null;
		SetInteractionHasChanged(false);
		return;
	}
	_defectModel.CreationDate = Convert.ToDateTime(date);
	SelectedDate = _defectModel.CreationDate;
	if (IsForConstrs)
	{
		if (AllConstrs)
		{
			SetInteractionHasChanged(true);
			return;
		}
		if (Nconstr.Count > 0)
		{
			if (Nconstr.Any(i => i.IsChecked))
			{
				SetInteractionHasChanged(true);
				return;
			}
			SetInteractionHasChanged(false);
		}

		SetInteractionHasChanged(false);
	}
	else SetInteractionHasChanged(true);
}
}

Everything works fine when I open the Calendar first time, there is no Date that was selected.
But when I open my page next time, the SelectedDate is exactly that the previous was.
How to disable that?
TIA.

Would it be fixed? Or any suggestions about how to resolve the issue?

Hi @denmusic1992 👋
As you may have seen @rebeccaXam is no longer with us hence the nuget is not supported by anyone.
Regarding your problem: is the date selected when you get back to the page with calendar? So you have flow like Page with calendar -> opens new page -> New page -> goes back to page with calendar -> Calendar page
