I have encountered an odd issue in using the Sandboxie v 5.33....

Hi guys,
 
I have encountered an odd issue in using the Sandboxie. When I run the Spotify windows app normally( without using the Sandboxie) I can access all elements in this app by Inspect.exe such as buttons and so on...But when I run the Spotify windows app in the Sandboxie I couldn't access its elements. How could it be possible?
 
The first attached image shows that I have used "The Spotify Windows App" outside of the Sandboxie. As you can see an element of the Spotify can be detected by the windows Inspect tool.
 
But in the second attached image, I have used "The Spotify Windows App" by the Sandboxie. As you can see when I wanted to detect an element of the Spotify windows app, the windows Inspect just draws a yellow border around the Spotify app and I couldn't access any elements.!!!!!
 
I would be grateful to explain this issue to me. Should I need to set any configuration in the Sandboxie or I don't know anything else?
 
Sincerely,
Alireza
