Make sure you follow fatkhulla's response below, and you can also look at the video instructions here: http://endnote.com/kb/82228 but don't skip Fatkhulla's last step.
Remember that you also need to make sure the output style you are using is selected to use the correct column of the terms list. Edit> edit output style, edit "your output style" -- as in the image attached. Then Save as and give new name (or save if it is an option). Then in the document make sure you are using the newly named output style on the Endnote X7 ribbon or toolbar. (not necessary, if you were able to "save" -- but never give it the same name if you have to choose "save as"!)
I always have the terms list update options firmly off in the preferences settings. I don't want endnote to assume I want things in my terms list. -- have you tried turning them off? see this preference option in the attached image (for endnote for windows, these are accessed via Edit, Preferences in Endnote)
Does your output style have the Journal settings to use the correct abbreviation settings (see image attached)?
If not, then it will use what is in the Journal field.
Are they in your journal terms list? If not, then it will use what is in the Journal field.
Are they in your journal terms list correctly? If not then it will take the wrong item from the right column.
