Just following up here since I've also responded through the Tapspace FB page. When adding libraries to a Finale file you should import the file rather than load. Know though that doing so creates duplicates of the default Finale text expressions.
The better option is copy/paste.
Mac OS 10.12, 10.14, 10.15, Win7, Win10
