Too bad :( In my case I do suspect a set filter because the other form doesn't show the same behavior.

BTW, I was trying to prepare a test case for Cesar and I used my exact form in question, but in the case scenario it didn't show the behavior (though I adjusted the filter condition and it may resulted in more records showing than the original).

Yes, very puzzling problem and extremely annoying :(
