Rune Page Drop-Down Menu Bug After Saving [CLIENT]

After saving a rune page using the "SAVE" button, the drop-down menu to view and select my other rune pages does not display them. It only shows the current page. If this happens, I have only been able to bring it back by logging out and then back in.

Fortunately, as a work-around, it does not happen by switching pages and using the prompt to save.
