can't update the citation and bibliography


I am using ENDNOTE X9 with Microsoft 365. I save the new style of citation format into the endnote style. But when I cite in the Ms word, the citation format can’t update. The appearance looks like this “[Wang, 2015 #2]”. Actually, it should be only appeared “[1]” . When I click to the update citation and bibliography, it doesn’t update. Also, it doesn’t show any error messages. What can I do to make it right? Thank you
