MTX bugged

The game wont let me put on a lot of MTX, I bought, while standing in my hideout.

The "Reclaim MTX" window simply says:"The "xyz" mtx you are trying to use is currently in use by another character or placed in a hideout. you can choose to remove it from a character or Hideout below."

Thing is: the "reclaim" button is no where to be seen.

I tried to put it on a mannequin, same problem...
