I just realize that the Single view mode of Collapsed Topics is showing only the activities not the sections. Therefore all the texts and hyperlinks in the section descriptions are not showing, if a user is in single view mode.
Is there something I am doing wrong? Is there a way to make the single view mode to show sections instead of activities?
For example, there should be texts which describes learning objectives, resources in this section. However now it is only showing the SCORM package.
