Arcade controller button mapping issue

[oodles]

Pi Model: Pi 3 Model B v1.2
Power supply: 2A
Retropie version: 4.8
Built from: Pre made image
Arcade controls used: https://www.amazon.co.uk/Fosiya-Joystick-Buttons-Raspberry-Cabinet/dp/B08HLZ4NJ9/

I have used the stick/button set above to connect to the raspbery pi and the button mappings are incorrect for player 1.

I've attached the buttons the same way to both usb controllers but the buttons are still mapped incorrectly for player 1.

Both players are connected and configured like below where the K number is the position of the port on the usb controller:

K4(Y) K3(X) K5(L)
K2(B) K1(A) K6(R)

I've tried plugging them into different ports but I always get the same issue which is player 2 buttons are mapped correctly like so:

Fighting game:
Punch Punch Punch
Kick Kick Kick

Two button game:
X X X
B A X

For player 1 the buttons are:

Fighting game:
Kick Kick Kick
Punch Punch Nothing

Two button game:
A X X
B X X
