Samy, Not sure if you received my email response but ill copy my reply here for visibility just in case.
I created a copy of the screen to take a look at the actions and Im noticing you have 2 Generate Report actions. One on the Button, and one OnScreenLoad. Was this intentional? The OnScreenLoad generation is causing the error message to appear here, and appears to have no filters at all.
Thanks Samy.
