Interesting. Can you make sure that you haven't wired column and drive across the normal switch closure so the diode isn't in play? I.e. green and white are connected directly when you close the switch instead of via the diode - outer lugs switched round.
Here's my theory: These switches were changed from a front to a back mount at some point as witnessed by the screwholes. Cables were just soldered on as they were without reversing the outer lugs and flipping the diodes. There's your problem...

I like that theory and yes I did wonder about those screw holes. Ok so swap white cables to green and leave diode in current position ? Sorry I’m rubbish at the electrical bit

Sorry I’m being really thick I don’t understand that last message , really appreciate the help
You unsolder the white cable and the diode and solder them to the tab on the other side. The leg of the diode which is on that tab currently goes to where the white cable was. Green stays as is in the middle. So reverse the outer legs. Maybe start with one to prove the hypothesis.
To explain what is happening here: there are two switch tabs and an unconnected tab here. The unconnected tab should have white plus unbanded end of the diode. The banded end goes to one of the switch tabs (usually tab closest to mounting angle), the green wire goes to the other switched tab (usually the middle one). This way you have green - switch blade 1 - switch blade 2 - banded end of diode - unbanded end of diode - white. Incidentally what you see on the photo posted yesterday. You currently have green - switch blade 1 - switch blade 2 - white as the unconnected tab isn’t wired in correctly. Just unscrew one of the switches and you’ll be able to see this.
You should check why mounting was reversed as that can have implications on how the switch holds up to the balls hitting it.
