If you're still having this issue, I have a psuedo solution.
Create a mapkey that generates the pdf and saves it to a folder/desktop. Then run the mapkey whenever you want to make the pdf.

Okay yeah, you should just be able to click Drawing Models on the Layout tab and click Del Model when the menu manager pops up, then select the incorrect model.
