Missing Terms in the Exported tab delimited file from SDL Multiterm 2019


I have an issue in SDL Multiterm 2019, the term "Partner Practice" is in the termbase as per the attached screenshot number 1. But while trying to search on it the tool is hanging and no result displayed as per screenshot number 2. I have tried to export the terms to tab delimited file and tried to search for the term and I couldn't find it as screenshot number 3.

Please check and advice.
