In further review we have found the following:

The form prints every time regardless of removing the form from the return via the active forms list. 

At no point is the "Filing Instructions" visible on the All forms list.

It shows up on the Forms in Use list when active, once removed it does not show on the forms in use list, but it prints even after being removed and not on the active forms list.

During the print job it adds the form back to the Forms in use, thereby printing the form.
