Template Manager object's approval status or permission group does not match with Parent Drawing Type or Sheet.
The Template Manager object's Approval Status or Permission Group does not match with the owning Drawing Type or Drawing Sheet object. The Template Manager holds the information of the template. By design, a Template Manager object must have the same approval status and permission group values as that of the owner object (Drawing Type for Volume and Orthographic Database Query Drawings, Drawing Sheer for Composed Drawings).
When the Approval Status or Permission Group value of the parent Snapin/Sheet was changed, the value did not propagate to the Template Manager object.
This problem can potentially stop creation of new Drawings under the Drawing Type or cause problems in deleting the Drawing Type or Sheet.
What You Should Do
Run the Clean Database custom command, select the objects, and click Clean Now. This operation sets the correct approval status and permission group values on the Template Manager objects.
