Selling Online eCourse - Licensing clarification

Hey all!

I am planning on purchasing a PowerPoint presentation from GraphicRivers. I’m creating (1) eCourse to sell with a one-time fee on Teachable or Podia. The eCourse will be split into multiple videos using a presentation template. I had a few questions that I wanted to double check with.

1- The eCourse will consist of videos of me using the presentation template as well as a downloadable copy of the same presentation (non-source, non-editable copy) for the users for their reference. Does this fall under 1 or 2 extended licenses?

2- Does this constitute as a series?
a- The template is under GraphicRiver. Does the same license info apply from ThemeForest?

If you could help I would greatly appreciate it!
