I have to reorganize Multiterm 2019 constantly, otherwise it won't show results. Annoying and time-consuming.Can this be avoided?

I have started using Studio 2019 and MT 2019 last week and while translating I have to reorganize the MT database constantly otherwise it won't show results.  Now also terms that were confirmed by the client won't show up. But as soon as I add and confirm the same term, it is shown in Term Recognition, but only for a limited period of time. After a while the term won't show up again and I have to re-add it to the database.
