I don't see a way to change the screening rules until you reach the screen results page, and since the screen is currently failing, you can't get there.
One thing you can try is renaming the screen report.
Go to your Screen Reports, select the report that's generating the error, choose Save As, and give it a new name. That may bypass the problem and allow you to continue working until we have a permanent fix in place.
I figured out I could just create a new screen with the same universe, ranking, and rules and it will work since it just gets to the default report. Unfortunately I figured that out after the open and missed a trade in DAKT which would have been quite profitable quickly.
