If the AUCTION for the listed item is over BUT
the item is still available (active, enabled, not expired),
then we should continue display the item as currently been done (disabling Hide Auction once Finished) but without the Auction Finished display over the item images in searches or categories. (refer image)
Why?
Customer/User when see the auction is finished, assumes the item is now not available for sale. Basis 6 out of 9 feedbacks.
Possibility with existing feature:
You do have setting "Hide Auction once Finished"
So if that is not enabled, and the item /qty is still available for sale, remove the auction finished green block from item images for sale, so seller do not get confused with availability.
