Entries in a calendar view show as AM. When I view the detail screen, they show as PM. When I go to Edit, they are AM. When I changed to PM and save, for a moment they stay as PM, but once Glide applies the correct time format, they switch back to AM.

Also, when I check the spreadsheet, the time correctly shows PM there.
I do have the spreadsheet set with the correct locale and timezone.
