I read a thread that said this was addressed in FileMaker 15 for number formatting, but I see the problem with date formatting. When a date field is formatted as a pop-up menu, the date always appears in MM/DD/YYYY format. On the left is the pop-up version, and on the right is the Edit Box version. This is on a UK system with a file that was originally created in the UK.
Did the bug not get completely addressed?
