Microsoft Teams Misbehaving!

Has anyone else encountered the problem with Microsoft teams where the application will follow the viewport when you switch to the desk the application is on.? However if you navigate the pages in the desk afterwards Microsoft teams stays in its place. I have the following styles applied: !UsePPosition, !UseUSPosition but it still misbehaves. Is there a style I can apply that will correct this issue? I am on FVWM3 1.0.6a
