Issues uploading course lessons in LearnWorlds

Hey everyone, I have recently been working on this CRM platform called LearnWorlds uploading course content for my company. Unfortunately, the students cannot access the video recording after their session with the instructor is over. So far it has worked fine but there is one course in particular that is not uploading. I was wondering if you could give me some advice or feedback to solve this issue and avoid it from happening again. Thank you so much and your help is much appreciated!
