The exported enex file has problems with the new version.

For those who want to migrate to Apple Notes.  
 

I tried to export the notes through the enex file and import into Apple Notes, I noticed that some notes were untitled.  After importing Apple Notes stopped syncing.  I redid the process using Evernote legacy and everything worked correctly.  If you are migrating to Apple Notes then you should use the legacy version of Evernote to export files.
