Journal term list

I am using endnote 9 in mac. 

Q1. Whenever I generate a new library, the journal term list is completely empty. I tried to import it according to the guideline, but the journal term list folder is missing. How can I fix the problem?

Q2. I tried to manually add journal term list (e.g. PLoS computational biology, abbreviation 1: PLoS Comp. Biol. etc). However, the existing reference’s output style is not updated according to the update of the journal term list (e.g. full name of journal is not changed to the abbreviated journal name). How can I fix this issue?
