AutoCad :: Remove Model Page Setup Entry From List Of Page Setups

Using Acad 2010

Is there a way to remove the *Model* page setup entry from the list of Page Setups in the Page Setup Manager? This is the first time I am seeing *Model* in the list, and I suspect that it the reason I am not able to generate a PDF for this particular drawing. When I try, I get the following error:

==================================================

I have this idea that removing *Model* from the list will do it. In addition to causing PDF creation failure, I believe it is also responsible for forcing the Model to always be in the Publish list, even though I have unchecked the "Include model when adding sheets" option. I can remove it from that list manually, but it comes back every time.
