Issues with MAIN NAVIGATION pages on website caused by Courses (Digital Products)?

I have been working on creating a course on my Squarespace website and since I began the digital product setup, I have noticed that all of my MAIN NAVIGATION pages on my site will moved down into the HIDDEN PAGES section. I have been having to add all of the moved pages back onto the main navigation section in order for my pages to be viewed and accessed almost on a daily basis. At first, I thought my assistant had accidentally moved the pages down, and not realized it, but when this has continuously been happening on a daily basis, and I am having to manually put the pages back where they need to be on my website, I figured it was time to reach out and see if anyone else is experiencing this issue and/or if this issue has been made aware of and if a solution to fix this problem will or is available. I am including a screenshot of what happens every time I log on to work on my website.
