Can't delete markers on UWP

Hello,
On attached Zip, you can find a sample app. The use case is the following :
- On load the Map have a set of Markers
- On click "Add", a marker will be added
- On click "Clear", all markers should be removed.

On Droid app, this works well. On UWP, the 2 first steps are ok. The clearing doesn't work.

Thank you for advices,
Olivier

Has this issue been fixed? I am using  custom markers and when using imagerylayer.markers.clear() the pins do not get deleted from the map. However the markers collection is empty. I am using sfmap version 18.3.0.35.
