glitched masterys

so before I went into a ranked game I checked out a persons profile on league it was someone is a recent game I played against, I checked out there runes and masterys, and then qued up for a game , this was ranked and I waited my turn to pick my champion, as I picked I, I picked teemo top, but as I was trying to change my masterys it showed I had 15 mastery pages all from that one guys profile I checked out , I was like WTF , and then realized it was from that one guys profile and they were not my own , I was really confused , but there was nothing I could do about it so I tried to choose one of the pages for masterys and all I got was a error code pretty much saying error cant find ..... so by the time I realize wtf I cant do anything I try to change smite ( cuz I was top ) and it wouldent let me change it either , so there I am trying to explain this to my team and bam all I get is stfu etc etc etc fuk u teemo etc etc etc ima a troll now etc etc etc , and this is complete bull shit , I m in a game in ranked and cant chose masterys , and on top of that its showing 15 pages of someone elses masterys , and wont let me chose any , nor are mine there at all, so im in a ranked game as teemo with smite as top with no masterys and getting cussed out and trolled and reported all due to a glitch in the system .....................
