Hi Thomas,
The SP LMS component may have had a corrupted installation. I have reinstalled the latest version, and everything is now working fine. Please check it and let me know if you encounter any issues.
Tips for You:
If you're new to SP LMS, I recommend checking out the Edulif quickstart package on a local installation. This will help you understand how courses are configured and organized within the SP LMS component. It's a fully functional Joomla course management system and can serve as a great reference for redesigning your site.
You can explore it here:

Feel free to reach out if you have any further questions.
Best regards
