[Publisher-Section Names = Gibberish Text in PDF Export]

Thanks! I changed the font on my Master Pages and it seemed to do the trick. What's odd is that particular font is used within other parts of the book and it displays fine. 

[Publisher-Section Names = Gibberish Text in PDF Export]

Update! I had a crazy idea to open this project on an older Mac running Publisher v1.10.4 and...it worked! Must be a bug with 1.10.8. 

[Publisher-Section Names = Gibberish Text in PDF Export]

Upon export of my book to PDF, all the section names in the upper right of my book pages are saving as gibberish text. This doesn't make sense because I'm using the same book template I've used in the past with this version of Publisher (1.10.8 on Mac OS Monterey). BUT, the book name on the left side (using same font) looks fine. AND, one subhead within the book doesn't look right when saved (supposed to say "Benefits). See attached.

I've checked the following:

-Font is installed and only one version/copy (Avenir Next)
-Text looks fine in Publisher
-When opening in Acrobat, all fonts are loaded.

Any ideas would be greatly appreciated, as this snag has delayed the publication of my book. Thank you!
