Razer Huntsman Elite lighting imput lag

Hello there, bought huntsman elite a while ago, out of the box it had the common "sticky keys" problem so I played without wrist rest plugged into my computer for a while and everything was fine, then I discovered the firmware update so I decided to try it. And after the instalation everything was fine besides now the response time of the lighting effect and the key press is like 5-10 seconds. For example when I press the "fn" key the whole board lights off in three parts and 2 seconds intervals, and when I release the button it takes 3 seconds to light up again. I'm kind of lost and upset because it prize tag haven't suggested any problems. Anyone had the same problems ? Or maybe you guys have any ideas, thanks in advance. :)
