Deletion of display assignments
A description of this resolution:

'Deletion of display assignments' resolves the following:
- Operator Station
When displays and the display variable “Controller” are deleted, the display assignments are not deleted in the system list. References to displays/display variables that have already been deleted remain in the system.

The underlying cause is:
- Display assignments are administered centrally by the loop function and not deleted.
