Summoner names in Champ Select and Post-Game Lobby.

Once I enter into a lobby, the chat will show my teammates or enemy team joining/leaving, but everyone's name looks something similar to this - (bc42e85-a69b-5acf-a8d3-1f606eb7ce joined the lobby). This has happened for both post game, and champ select. This is only how it appears in the chat for both. This doesn't really affect my game or anything, but wasn't sure if it was important or not either.
