SiGma keyboard CTRL,WIN,ALT keys behave as shift

[OfirTIM]

Hello fella's!
I've recently installed mint as my primary, was tired of using windows for 10 years.
I bumped into a problem with my keyboard that when pressing keys CTRL, WIN & ALT, it behaves as SHIFT key, and does not let me do anything in particular.
I've tried working with a few open-sourced drivers from AziokBD-kdms, but none seem to work, I currently can't change language from English, and cannot do any short-cuts on my keyboard, as its all just SHIFT.

here's my Bus device list from

I've tried everything, including replugging my devices and putting them in different ports, I've tried changing Grub rules which resulted me in the pain with recovery mode and couldn't access my linux system for a few painful hours.
My mouse is detected as SiGma too but it works just fine and does not have any problems.
