is necessary click in “update list” in the “Term list” box

otherwise， is necessary click in “update list” in the “Term list” box in order to link the previous references with the term list， Thank you very much for you “amazing”  answer， I spent long hours trying to solve it till I found this forum and your answer!.  Only， you will find references without assigned abbreviation and so on.  ， I would like to add that if this procedure  is applied on an already created library，。
