Rune page bug

Hi, I've encountered a rune bug. For example, If my rune page names were 1, 2, 3, 4, 5, 6, 7, 8, and 9, I changed my rune page 5, which was +15 ad to +12 armor pen. After I SAVED the change and got in a champion selection, the updated rune page sets are not shown, instead there are the old ones.

After one whole game, I re-check my rune page settings, the new pages are there and successfully saved, however, if I am playing another game, the old pages would still show instead of the new ones. This wouldn't be fixed until I re-log in the client.

I know I can fix this by re-logging, but it's VERY inconvenient to do so!!!!

I've had this bug for weeks and never had it fixed after patch update. If any of you have the same issue or know how to fix it, please tell me.
