Logitech K585 CMD button on Mac no longer working

OK so I have this setup with my personal mac and my windows computers connected to a KSM using a logitech k585 keyboard.

All was well until there was a bluetooth issue today, fixed it, but now my logitcech keyboard has issues with the mac.

When I hit the CMD button and try to copy or paste, I get ÍŠand so fourth.

Yes, I have gone to Sys Prefer>Keyboard>Modifer, yes I have checked and yes they are set correctly.

Yes I have toggled, switched, done all that, NOTHING works.

The only thing that helped, I switched the CTRL button to be CMD, now I can cut and paste with CTRL like I would with CMD; yet CMD itself STILL WILL NOT WORK.

Yes my mac is up to date.

WTF?

Worse, my typing at times stops, like the connection has been lost, so I have to turn off the power button on the KSM switch then turn it back on.

Is there anything I can do, or do I have to accept the CMD will never work as intended again because either Mac or Logitech or the KSM suck?
