Razer Naga Pro numpad not working properly

Hello, as of late i’ve been having issues with my numpad on my razer naga pro I bought last year, and I have no idea how to fix it. Specifically the buttons 3, 6, 9 and 12 have been malfunctioning entirely.

3 has been typing out 321
6 has been typing out 654
9 has been typing out 987
and 12 has been typing out ´+0

Essentially the upper part of the numpad has been triggering the lower part of the numpad for some reason. I have tried removing and reattaching the side plate but to no avail. Even cleaning the contact pins hasn’t helped.

Even connecting the mouse to a separate computer has the same effect, there are no macros on the mouse either. All of it’s settings are standard and have never been changed.
