Reference not working

I am using Word 2013 and EndNote 6, an dam having a problem with my bibliographic reference. I am currently using a style where the name of the Journal must be abbreviated. However, in a few cases the Journal is not abbreviated within the created reference list. I have made changes by using the Open Open Term list, but the problem still persist for  few Journals. How can I get over this issue?

See the following FAQ to explain how to handle abbreviations.  I also suggest turning off the auto-updating feature in the Endnote preferences for Term lists (edit >preferences  – term lists, until the 2nd and 3rd boxes).
