Settings not saving

I’m trying to select what categories appear on the home screen (Movies, Music,..) but the selected settings in the Skin settings menu are not saving. When I deselect a category the second I touch anything else the selection is on again. Same thing works in the default theme but not in Aeon Nox which is my favorite theme. I’m a Kodi beginner so I apologize if I missed something obvious. I downloaded Kodi from the Google Play Store. Any solution to my problem?
