Catalina 10.15.7 - Monitor rotation

I have two external monitors on my iMac, but rotated to 90 degrees. Since last night's update, I can only rotate one at a time. If I set the third monitor to 90 degrees, the second reverts no rotation.

Does anyone know if there's a fix for this?

Thanks

iMac 27″ 5K, macOS 10.15

I'm experiencing a similar regression since 10.15.7. I have a single monitor rotated 90 degrees. Since 10.15.7 my rotation preference is lost every time I disconnect and reconnect, it reverts to standard orientation every single time. 10.15.6 worked fine.

10.15.7 really broke the code that deals with rotations.

ColorSync is a suspect: https://apple.stackexchange.com/questions/340407/macbook-doesnt-remember-screen-orientation/409236
