[Client] Cannot rename rune page

My Third rune page is stuck with the name "Empty". If I try to change the name without adding / removing a rune, I cannot save. If I change the name and add / remove rune and click save, the name spontaneously changes back to "Empty". Only one rune page has this problem and the issue has only existed for a month. I've had this rune page since my account's initial creation back in season 2.
