Logitech G710+ keyboard stopping working correctly on Yosemite

I upgraded to Yosemite and my Logitech G710+ keyboard command, control and option keys no longer work. Nothing I try seems to fix it.

I've installed the Logitech software. Nada

Keyboard preferences show proper mapping for all keys.

I reset my PRAM. Nope. As a matter of fact, I had to plug in a different keyboard to even reset it. The other keyboard command, control and option keys work fine.

This appears to be a problem specific to this keyboard as my other generic $25 keyboard works without issue. Unfortunately, I really hate my other keyboard compared to the G710+.

Help!
