.tmx converted with Glossary Converter missing customized fields and values when reimported into Studio TM

Hello,

When I convert a Studio TM with custom fields and values into a .tmx using the Glossary Converter  and then reimport the .tmx into a Studio TM (with the same fields and values available), all those custom fields and values are gone. Is that normal? I opened with Notepad a .tmx produced by directly exporting a TM into a .tmx using Studio, and the .tmx produced by the Glossary Converter and there are some differences. 

Thanks.

Beatriz.
