[Client Bug] Rune page names not saving properly

Since Patch 6.1 changing runepages faced me with a weird bug. While I'm able to change the actual content, I can't change the name, thus not knowing what page does what for me while in champ select. Sounds like it's not so big of a thing, but once you have 20 rune pages you'll be glad to not need to look up each one.

Details: When changing the name of a runepage before changing the content, then removing or replacing any rune will result in the name resetting. Also, the "Save to Runebook"-option is unavailable. If the content is changed and then the name, the save-button will stay available, but the name won't actually change. It just jumps back to what it was.

Workaround I found: To change your runepage names, there is still a workaround I found. You need to change the content, not save, rename the page and instead of saving you click the "League of Legends"-logo in the upper left of the client to return, which will face you with the "You got unsaved changes in your rune pages. Want to save now?" message. Click 'yes', go back to your runes, and the name of the page will be saved. This workaround does not work for already assigned names.

Technical: EUW; 15.01.2016 was the first appearance of this bug I noticed.
