Ingame Marked for MONTHS wrong language!!!!

Common GGG, cant you address this???? Any words about it???? Maybe a simple language setting???? How comes that my game is and was ALWAYS in german but my marked is ALWAYS in english and i NEVER can search for something since the keywords are in english but the searched items are in german and thus not compatible.
