Hello.
Remove "Design View Representation is locked" message in [Primary], if we use "Delete Section View".
If "Section View" is used in [Primary] view, it shows the message shown on the image below.
If "Delete Section View" is used, it will still show this message all the time.
If new "Design View" is created and immediately deleted, it will not show this message again.

Best regards,
Rene Repina
