SelectionChangedCommand issue on CollectionView

In my app from main page when I select an Item it navigates to next page as per selected Item ID, but when I return back to main page and try select same Item again, I can't select same Item,
Note: this is happening only with Xamarin Forms CollectionView, but with ListView it works fine,
Latest version I;m using
Microsoft Visual Studio Enterprise 2019
Version 16.6.2
Xamarin 16.6.40
Android SDK 10.3.1.4
XamariniOS 13.18.2
