Skalp - scene selection bugs?

Just paid to have Skalp in Pro 2021 on iMac.

Are there bugs with scene selection in Skalp?

I’m not clear on whether I need to have the Skalp dialogue open or not when selecting a scene.
With dialogue open, if I go to change the scene using the normal button along the top of the screen, I just get a spinning wheel and have to Force Quit.
If I change scene with the dialogue closed it doesn’t load the camera in the right place facing the section plane.
So seems I have to, select scene with Skalp closed, Open Skalp, make changes, close Skalp, change scene, open Skalp… very slow and frustrating
