Team builder rune page bug

If you open team builder and pick your champ/runes/mastery then don't leave but go to your profile and change the rune page, then go back and DON'T save it shows the runes like you DID save. I don't know if it actually alters it but it does look like it. Not a big deal if you see that it happened but it would suck if someone ended up with the wrong stuff. Leaving the team builder and reopening shows the runes back to normal without having to actually go change it back.
