spotted an odd problem where Updated submissions weren't being counted under New Submissions. They'd still appear in the list but the counter wouldn't go up.
Turns out there was a "d" missing in a column name in that bit of the code. So I typed that "d", found that it fixed the problem after a quick test, and submitted the change to the live site. Easiest fix ever. :P
Should work now. All New Submission counts have been recalculated. Any more weird miscounts should be reported via a Support Ticket!
