Problem with new Parallels Remote Application Server version 18 update

I'm a Mac user (Catalina v10.15.7) and upgraded to Parallels RAS version 18 today and my remote desktop window does not fill my screen. Instead, the window is shifted upwards a few inches so I can't see the top of the RD window and there is a black bar underneath the RD task bar at the bottom of the screen. Also, my mouse clicks lower than it points (the same height as the black bar at the bottom of the screen). This happened only after I downloaded the v.18 update. Please help! Thank you!

 

Yup, I got this too. The work-arounds options I did on my RAS console or at the end client in the meantime:

1. Downgrade my parallels client from 18 to 17
2. on the RAS, set my Desktop size under Properties from "Use available area" to a fixed resolution
3. Use the web client

Hoping there will be an update to the RAS or client app that can fix this soon.
