Enterprise Theme Global Design switch error

Description

When trying to switch the space theme back to *Use Global Design*, we are hitting into an Error 500 NullPointerException error page.

We were previously using the *Use Global Design* setting and switched to the *Bernina* setting for testing purposes.

We then encounter the error when trying to switch back to *Use Global Design*.
 
Steps to reproduce
If I change the design from Global to Bernina everything works fine. But if I try and change back to Global Design I get the Error.
 
Expected
If I want to switch back to Global Design, from Bernina, the global Design should appear without error.
 
Actual
When I switch back to Global Design, from Bernina, I get the error

Note:
This only happens in a DC environment. Tested with 7.0 DC
