Try to remove your termbase from the active project and then add it again without restarting Studio. It works for me.

Thanks Stepan! I tried that too. It seems that it is an inherent issue. Don't know what to do. My translations are full of terminology.

Yes, I have to admit, it didn't work for me either. I only could make it add new terms but the terms that were already there still didn't show up.

What really helped me was reorganizing my TB with Glossary Converter. To do that, choose sdltb as output file format, then drag and drop your problem sdltb file. GC will create a copy of your termbase with .output.sdltb added in its filename. I don't dare to say it will help you, but you can try it either.

Thank you, Stepan! I will try that.
