new terms added in Trados Studio 2019 cannot be found in Multiterm 2019

I have added new terms to a termbase in Trados Studio 2019. After closing Studio and opening the termbase in MultiTerm 2019, I could not find the new terms. I noticed that the entry numbers of a  number of terms in the Termbase Viewer differ from the entry ids of the same terms in MultiTerm. What should I do?
