Razer huntsman 1 key and lightening bug.

Hello, as in tittle, i got Razer H v1 . After some days some keys light in the other color than other ones i choose in razer synapse. And one key ( in my case key “y”) doesnt work correctly. Sometimes it doesnt work at all, sometimes it works 8 time when i press it about 10 times, sometimes it type double or triple“y” with one press, only this button works like that, everything is okey with other ones. I couldt find this topic in any forums so i came here.
