How to remove irrelevant eLearning courses from the 'Insert Existing Courses' options?

Removing irrelevant SCORM courses from the 'Insert Existing Courses' options.

Content

Hi,

I'm just wondering if it's possible to remove irrelevant and/or non-existing eLearning courses from the 'Insert Existing Courses' list. So far I've tried going into the SCORM folder via FTP and removed the old versions, but they still appear when you do a search for 'Courses added with the SCORM Importer' and select 'Individual SCOs'. I don't know another place in Learn where old SCORM imported courses would be stored? Any helpful tips would be greatly appreciated.

Thanks
