K95 RGB Gkey only one key at a time/Ghosting?

I got a brand new K95 RGB keyboard and tried to set G8,10,11,12 keys to WASD, but it seems keyboard can only register one G key presses so if i press G8 and G12 at the same time, only one key will register, is there something wrong with my keyboard? or does the the full antighosting doesn't apply to Gkeys
