Huntsman Mini anti-ghosting(?) problem.

I bought a huntsman mini with clicky switches the other day and when I was playing CSGO, i noticed that sometimes some keys would not register. I thought it was because of some faulty switch I got out of unluckiness. However, after getting a replacement from the retailer, the problem still happens. I've done some research about it, and updated the keyboard's firmware, reinstalled synapse, even reset my pc and cleaned the USB ports. But it still persists. I used some keyboard testers online, but it was hard to replicate the problem, so I am wondering if it has to do with the game itself. This didn't happen even once with my old blackwidow TE, so it adds even more to my confusion. Did anyone have the same problem? How/have you managed to solve it?
