I would like to report a bug

Okay so I was looking up a summoner and looked at their masteries, then the party leader started the ranked queue. I clicked the profile button on their account, then clicked it on mine. Went back to lobby screen and found a match. I was queued up for Mid/Support. Someone declined twice before it was accepted and launched into the actual lobby. Upon looking at my masteries to change then to support, I could not change my masteries at all, because they were all the ones that the person whose profile I was looking at had. I could change my runes, but when I tried to change masteries, I got an error message. I fixed it by going into the mastery editor, and all was fine after that. But figured I would let you know about that.
