Bugged end game screen

For background knowledge, I have both the alpha, PBE, and default client for League of Legends installed. My primary client has the korean announcer pack installed. Other than that, there are no changes to any of clients themselves. In the champion selection screen of this game, after choosing all our champions, the client bugged, with the roles of each player displaying over the textbox, and the text in various locations. {No screen shot unfortunately, as I seem to have run into this issue quite a few times today} After the game, the end game screen was as shown, the other tabs display correctly, however whenever I go back to the overview the screen is as shown.
