[CLIENT] Weird rune page behavior in edit mode during champ select

This bug is somewhat weird to describe but I'll do a step by step of what happened in the video saying the Action I did and the Consequence it had. I had a fresh start of the client going straight into champ select.

A. I had page (1) selected from my last game by default and opened edit mode C. The client selected Inspiration by default in edit mode

A. I closed edit mode without making any changes C. Got the error "There was an error setting your runes page" and the client had rune page (1) selected in champ select

A. Opened edit mode with Inspiration selected again and instead changed it to rune page (1) and closed edit mode C. Got the same error as before and page (1) was selected in champ select again

A. Opened edit mode and page (1) was selected by default and changed it to (2) and closed edit mode C. Didn't get an error this time and the page changed to (2) in champ select

A. Opened edit mode and switched back to page (1) and closed edit mode C. Got the error message but the page switched to (1) in champ select

A. Repeated last step but with Inspiration C. Got the same result but without the error message

I've managed to do this bug consistently with the same things happening every time and if I vary the order of the pages I select the result seems to be the same. All pages seem to be affected by this until page (1) is selected and then only that page is affected. If any of the preset pages are selected as default in champ select from a previous game then the error won't occur. Also if you change the runes in page (1) the error won't occur either but restarting the client makes it happen again.
