Autocomplete not firing on screen

Summary:

Hi - we are having an issue where some of our autocompletes are not firing when the supervisor/manager are going through the screen, but it fails in transaction console after the transaction is submitted. For example, we have a rule that all pay changes must take place on a Sunday date and for myself it fires on the screen if the action date is not Sunday. However, we have recently had a couple of managers submit transactions that actually submit and then fail after the fact. Why is this happening?
