[Help] Cant hold down a key without it spamming (This is a problem for League of Legends)

So I just got my first mech, it is a Coolermaster Masterkeys Pro M and I am loving it so far. However, when playing LoL and holding down a key it wont let me keep it pressed. The screen basically starts having a seizure since it thinks that I am just spamming the key at like a billion presses per second and isnt realizing that it is actually being held down. What can I do to combat this? I know that mech keyboards are used to play league so is this just a problem with my keyboard and something that cant be fixed, or is there a way that I can fix this? Thanks
