Multiple sites managment issue.

First and foremost, The AaPanel is amazing.
When I am deploying more than 1 Django web app using Aapanel, sometimes when I restart the app (anyone among all), instead of restarting it stops/crashes/destroyed and all the modules have gone from the "modules" tab (in python manager).

It may be a simple issue but for resolution, I have to know what is the cause.
Any help will be appreciated.
Thanks
