I have some strange UI behaviour with ambience settings mixing up on 3.1.0.12 on Jolla1

Like set on silent (blue) ambience leaves me partially the remaindets of previous ambiences (black fonts of Glacial with red GUI of Salamander,...)

Now I recently lost the complete mobile settings menu items from the SettingsMenu. (No switching 3g, changing operator, toggling mobile net...)

Anyone experienced something similar?
Its like HAL from Space Odyssey 2000 slowly loosing its mind,.... pretty scary.
