Map stash tab is unusable

Ever since the start of the league, my map stash tab on standard has been this way, i cannot place any maps in it nor can I see any maps in it. Affinity doesn't work either, I'm having to keep my maps in my inventory and unwanted ones in random stash tabs. Remove only maps stash tabs are functioning normally, though they are not usable as a temporary replacement for the actual map stash tab as they are remove only.
I tested this on mirrage legue and I was able to place a map in the map stash tab and take it out normally, so maybe this is just a standard thing?
