Kingsmarch map device broken

The first slot in the map device says there is a map there but I can't click to open it for the rewards and the image of the map is gone as well. It happened when I tried to claim rewards.









I don't know how to do images but if someone tells me I can.

I think I had this before also. I fixed it by putting in a new white map where the blank space was and it allowed me to continue. Hope it helps
