I had this keyboard for months just updated to 51. The ctrl key is always a different colour from the rest even when I reset the colour. (Example if I set full blue , it will be another random colour) Also, preset stuff like "Reactive" , "Arrow Flow" etc etc doesnt work properly as some keys just turn to this weird greenish colour and for the "wave" effect it has the same problem as the first one I stated fix it quick please.
