Batch Import into Glossary Extension

I am using the batch import application (link here) to populate the Glossary Application Table (link here).

However during the mapping and the import, I have tried in multiple different ways to set the “parent”, which in my case must be the Glossary Application, but I can’t make it work. The Batch Import imports the data into the Main page. How can I resolve this issue? What do I need to change so that all the data are imported as children of the Glossary?

Thank you for your help.
