Shutdown the AppVM does not work correctly

The problem is as follows: when I am in Qube Manager and right-click on the AppVM, and then click on the shutdown - AppVM is turned off, but then independently turns on. That is, the shutdown command behaves like a restart. This problem occurs only with AppVM. Shutdown on TemplateVM works fine.

Have the strange feeling, there’s another appVM, which needs the VM (which was shut down) and therefor it starts it again.
Not a usual behaviour, cause it normally should shutdown the other VM too…

All AppVMs or just Whonix workstation VMs?
