I can't see this reported elsewhere. When I look at the 'Active' entries of the Bazaar/Auctions/Browse I get several entries with 'Time Left' of "Ended" and a Date and Time under 'End Date'. There are (usually) items at the bottom of the list with time remaining under 'Time Left' and grey shading under 'End Date'.
This is quite annoying. https://boardgamegeek.com/geekauction.php3?action=listopen used to show only auctions that are currently open/active. Now it shows quite a lot of auctions that have already ended, as far back as January 2015. And the active ones are at the very bottom of a list that should only show active ones.
