I've got a handful of extractions that appear to have blank criteria in all keycodes. But generating counts returns results, and looking in t_keycode I can see there are criteria for the segments in question. But from the front end, it looks like there's nothing there. It's blank in the graphical edit area and blank when I click display query. Switching to manual edit lets me edit the blank box. There's definitely criteria there, but I have to go into the back end to see what it is.
Anyone ever experienced that before? Any ideas why criteria might be invisible? I haven't been able to identify any pattern.
I have a vague memory of this happening before quite a while ago, but don't recall finding an answer and I couldn't find the post by searching. Apologies if I am double-asking.
