Alps.map - No water in the Lago Maggiore

Hi all,
not sure whether the topic fits here, however, I did not find any other suitable category so I’ll give it a try…
Briefly: I downloaded the latest alps.map and came across a strange bug. Whilst most of the seas are displayed correctly e.g. the “Lago maggiore” is missing. You can see the ferry lines etc, but the sea itself is not colored blue. Tried it on three different androids, all the same… Hope that is not related to climate change?! Any suggestions here?
Cheers
Andreas

Did you open multiple map files or just the alps.map file?

You’re right. It happens when you open multple maps. As long as you just open e.g. dach.map or alps.map the Lago maggiore is displayed. If you then add italy.map the water disappears…
