razer huntsman

Hi Recently I have bought a razer keyboard (Huntsman V2), and am using synapse software, I cannot use Ctrl + Tab to switch tabs in the browser anymore (Microsoft Edge). But all the non-razer keyboard works. Any thoughts Thank you

I have a Razer Huntsman keyboard and I really like it but for some reason, sometimes when I press a key down it will spam the key rapidly, even if I've let go of the key, and I'll need to press another button in order to negate it. It doesn't really bother me that much but I'd like to fix it...
