the journal title shows full abbreviated format not while in the Endnote is abbreviated

my problem is that when you generate the bibliography in a document. doc the journal title shows full abbreviated format not while in the Endnote is abbreviated. how I could fix? Thank you.

Endnote has a journal terms list which is unfortunately updated by default.  I would turn off that feature (see the  thread: Abbreviation & the Term List) and then consult the knowledgebase FAQ here and the video therein.  Also there are a number of threads you can find by searching the Endnote forums here with Journal Terms List.  Another one you could look at is the thread:“Abbreviation & the Term List” which gives some sources for the journal terms list!
