Hi,
This is not a support forum (its the customization forum) so we do not check this forum daily.
If you want any support from the vibethemes team, then please create topics in the relevant support forum:

--------------
Coming to your query, we generally show the excerpt content here, if you are using the front end course editor then its the short description that you add in the course.
By default the excerpt length is 20, you can change it from the wp-admin->wplms->miscellaneous->default excerpt length.
Hope this helps....
For any further questions please create topics in the support forums.
