Media black hole

Why is it that although some types of media end up in the regular WordPress Media library, (such as audio files), other types of media, such as course featured images, can only be uploaded into the secret Media folder that is specific to FluentCommunity and impossible to access otherwise? If I need to reuse an image in courses, I apparently can't view previous uploads, and I have to upload fresh image files repeatedly, which is duplicative and is super-inefficient.
