Language Filter Bug on League Friends App

So in being on holidays and not being able to use the proper league launcher for 2 weeks I've been using the App all the time and I've noticed some words are **-out without them being proper curse words.

The main word in question is "Ja" german for yes, I type this a lot and every time in caps or not it's starred out and it's not a curse word at all. Another was "Ebe =C" which means, roughly translated yea or airgo (more or less). I asked riot support and they said I should write this post thingy so here I am :D

For reference I am on the server EUW and I have an android phone. It would be nice if this was fixed so I can text normally with the Lang. Filter on so I don't have to see all the real curse words ^-^

Kind Regards, TheDwarfGirl
