Impossible to find established terms in MultiTerm 2021


I have established several termbases on MultiTerm since two years ago. Haven't been using it for a couple of months, I tried to open some estabished termbases by selecting them, I could not find the terms that I created...

I have created more than a hundred terms but I just saw one term in each termbase. What happened?

Could you help me to solve the problem, please?

Thank you in advance!

Kind regards,
