Cannot access transfer market through mobile app or web app.

The red circle above the transfer targets says I have 51 items in there. Obviously some sort of glitch as the limit is 50 items. When I try to open the transfer targets I get a message saying that the transfer market is not available at the moment.

This means that I cannot release these items, and also I am unable to buy any items as my transfer targets list is full.

Any advice or suggestions gratefully received.
