I deleted a bunch of test entries I created while testing (using the Polls add-on). While no entries are now listed, the unread count still says 45, and there are paging links as if there are 45 entries to view. When I click on the paging links, it just get "This form does not have any entries yet."
I am using the latest GF and Polls Add-on.
I wouldn't care so much about the count, but that number seems to get used to incorrectly generate the poll result %'s, which display on the front end.
