Users in the United Kingdom and Europe may set Deactivation Dates on their Application forms so that the form automatically deactivates on a specific date at the end of their grant cycle so that users may not apply after the grant deadline. Reports have been received that when users set these Deactivation Dates on a form, they will set the form to inactive prematurely.
Your form is showing the Deactivation message prematurely because of the way the dates are being handled.
For example, setting a deactivation date of 5/9/2018 - which is September 5th 2018 in UK/EU date format - will cause the form to show inactive because the system perceives this date to be May 9th 2018.
We have qualified this behavior as a Bug in our software. Our current suggestion is to manually deactivate your forms when your grant deadline is reached as we troubleshoot this matter further.
