Date format switches from correct format to stored value
I have a repeating grid that displaying the deadline for a document submission. This deadline is calculated using a declare expression. When I move to this assignment, the section that originally displays has the deadline date in the correct format (Jan 1 2001). After a couple seconds it then reverts back to the stored version of the data, as shown in the screenshot. This has never happened to me before so I'm wondering what is going wrong. Any ideas?
So even though the property itself is only Date, I set the control to Date/Time then chose the Date/Time option for read only formatting, and it shows the date in the correct format. Thanks for the input everyone.
