Yes, Miscellaneous and Medical information are not exported with the Family 5.5 option. Nor are the Individual Text Footnotes, Event Text Footnotes, Research notes or media files.
I'm guessing that if you want to make a GEDCOM to import into PAF, you might want to create an event Gedcom File, making sure to check Destination Group/Ancestral File as if making it to submit to the LDS Family History Center. You can find these options in your manual. You have more control over this type of Gedcom and can tailor it to include what you desire.
