I'm not experiencing the same problem. Ended items are there at the bottom on a mobile device or under the Completed tab on computer. For Buy it Nows anyway, I can't speak to Auctions specifically because I rarely Watch those.
As a workaround until this is ironed out for you, if you do a search on the item and click Completed or Sold listings at left, you'll see what sold and what didn't, prices disclosed.
