[BUG] Desktop Icons not Saving

I have a user with some desktop Icons, and I’d like to display new ones, but I’m not having any luck in getting them to save.

If I go to Show or Hide Desktop Icons >> For User >> username, I see a list of checkboxes with the ones on his desktop checked off. If I check off the others and click save, I get a notification “Updated”. If I refresh the page and go back to that user’s details, the boxes are not checked.

Any suggestions on what might be happening?
