Whenever i try to change the Timezone via the device details page on the bottom it just changes for a second, loads, and then goes back to the old Timezone. This is only happening on a few iPads we have, the other ones are working just fine and they have the exact same profiles and are in the same device groups.

The devices location is just as always in germany, but the time is US/Pacific.

This is extremly annoying for our employes, because thats like a 9 hour difference between Timezones, so i would appreciate some help on that topic.
