Masteries Name Bug [CLIENT]

I like to name my mastery pages after the champs they are used for and for some reason I can not name one Rakan . It always changes to ...an. I don't know if this is just my game or not I tried reinstalling league tofix it and it didn't to anything It does the same thing if you type in Soraka's name you get So...a. Can I get a heads up if this just me or the game? It's a little irritating. Thanks for reading this.
