I cannot see the content or course I create in Learning - others can

Issue: I can create a learning course and upload an online learning content but I cannot subsequently view the created course or content. Other people can view both. The same is true in vice versa - I can view courses and content that others create but they cannot view their own created content.

Security: I have tested this with all users having a custom role duplicated from the seeded Learning Specialist role.

What could be causing this issue and, more importantly, how can I fix it? Thank you
