Bug/Issue Museum bug on Mac

I am not able to donate any items to the museum in any of the slots under my inventory bar. They are still outlined in red like usual, but when I click on them with the item I want to donate, it's as if there's no slot there. I have been avoiding this by just using the tables that are located above my inventory, but I have just filled them up and am out of ideas. Has anyone else had this problem?
