To replicate the issue:
1. Create some regular waypoints or photo waypoints.
2. Go to "Manage" and delete waypoints either by using the trashcan or "Delete from database". The selected waypoints disappear from the list.
3. Return to map view and the waypoints are still on the map (and can even be moved around), although the list of waypoints is empty.
4. Quit OruxMaps and enter the app again: the waypoints are still on the map.
5. Quit OruxMaps and clear the RAM. Enter the app and the waypoints are now gone from the map view.
