Need help with double-typing keyboard

I recently bought the Razer Blackwidow Tournament Edition Chroma v2, and it was working fine for a couple of weeks until suddenly it began double-typing. More specifically, my Z and X keys. My primary game is Osu, and those two keys are the buttons I use to play. The X key double-types much more frequently than the Z key. Admittedly I do apply a bit of force when I press the buttons, but I believe it's no where near enough force to cause damage. I don't have any razer software installed. I have tried taking off the key-caps and blowing on them to get rid of any debris. These are the only two keys that double-type. What should I do? Link to video of it happening:
