Ctrl, Alt, Super and Shift of both sides registered as SHIFT_L

Disclaimer: This is my first day getting into Linux, if there is something I should not have missed please do kindly let me know.
As title described, all of listed keys are registered as SHIFT_L with same key code in xev:

KeyRelease event, serial 38, synthetic NO, window 0x2800001,
    root 0x1df, subw 0x0, time 365076, (894,-97), root:(944,750),
    state 0x11, keycode 50 (keysym 0xffe1, Shift_L), same_screen YES,
    XLookupString gives 0 bytes: 
    XFilterEvent returns: False

This issue happened on both Fedora 41 and Ubuntu LTS as I have tested today.
Looking online, I have tried to install Swoogan/aziokbd but the same issue persists both right after install and after reboot.
aziokbd/1.0.0, 6.11.0-21-generic, x86_64: installed
The keyboard works fine on Windows (dual booting on the same PC).
Both Fedora and Ubuntu were freshly installed with no extension or modification.
Keyboard layout: English (US).
I don't have spare computer or keyboard for swapping test. Appreciate any suggestion and pointer.

What keyboard is this specifically

Generally speaking, keyboards follow the USB HID device specification, which is universal and this really just shouldn't be happening unless it's some fancy ass keyboard with special macro features
