SCORM xblock missing navigation menu

Dear Open edX community,

I recently installed the SCORM xblock “GitHub - overhangio/openedx-scorm-xblock: SCORM XBlock for Open edX” on my Open edX tutor Palm.

I tried to export a course from eXeLearning to SCORM 1.2 or 2004 format to upload to my Open edX.

When I upload the scorm package in Open edX I can only see the first page of the course. A navegation menu is supposed to appear to move through all the sections of the course, or alternatively some buttons for “next” and “previous”, but it doesn’t.

I guess it’s some xblock problem because I’ve uploaded the same package to another LMS platform and to scorm cloud and I can see the menu and navigation buttons.

Any ideas or suggestions?

Thanks in advance. Best regards.
