There can be multiple reasons for a class section to not sync to PASI. 
Best practices it to first check for any Alerts or Rejections at the top of the PASI Compare Screen for Class Sections.

Issue: Class section not syncing to PASI with no alerts or rejections.

- In this example we see special characters in the Course Title or Description. 
 
 

 
PASI does not seem to allow unique characters:
