I found one more issue.
In Settings, choose to use the offline map.
And now:
1. Select "Lists" from main menu.
2. Select any list.
3. Select any cache from the list.
4. Select "Show on Map" from the context menu.
The map will appear. Up to this point, everything is fine.
Try changing the map layer (e.g. to satellite or hybrid).
The selected map will load, but the offline map will cover it.
After every move or zoom - the problem repeats itself.
Thanks for letting me know... also fixed for the next release!
