Bug in Team Builder searching Summoner

When setting up a team in team builder, if you search another profile, it will set your mastery options to their masteries. At least when my friend who is lvl 25 did this, the game did not start once we all said ready, since it was giving him level 30 masteries. I am not sure if the game will start if the masteries are for the correct or lower level than the profile who uses it.
