Champ Select Glitch

Okay so the following just occurred: I was in champ select for a ranked solo Q game and i was banner/first pick. I made my last ban lee sin, and now his portrait popped up on the right, and did not disappear, which I realize happens sometimes and i get stuck with that; now here is where it gets annoying. while waiting for my opponent to make their last ban, i checked my masteries page, and the portrait hadn't disappeared, so before i could close out of the mastery page, my pick came up and loaded up lee's portrait over the X button on the mastery page. As you may know, you cant click on anything within the portrait that may be underneath it...ie the X button, and there is no hot key to close the page, so now Im stuck not being able to choose a champ, and now get a loss of LP and a dodge penalty. Is there anyway this can be fixed (and potentially my LP loss regained)?

will be including a screen shot of what is stuck on my screen currently. as it is the remainder of the champ select

NOTE: Right at the end of champ select it switched to aatrox because the mastery box disappeared and i hovered him in an attempt to choose him, and this was left.
