[CLIENT] Wrong Map Shown in Client Match History

The Match History in the client lists "Summoner's Rift" as the map regardless of where the actual game was played (e.g. Twisted Treeline, Howling Abyss). There's a few games in my History that show Poro-Snax or Sweeper as my trinket, neither of which are available on Summoner's Rift. The detailed game page displays the correct map though.

1. Play a non-SR game.
2. Go to the Profile -> Match History tab in the client.
3. Check the map name shown.

All of the 10 non-SR games currently in my Match History incorrectly list "Summoner's Rift" as the map.
