Unable to save on Course Landing Page (solved)

I have completely filled out the course landing page. It has a title, subtitle, description of 265 words, all of the basic info boxes are filled, topic is filled, course image and promotional videos are both uploaded, and yet I cannot save or navigate away from the page.
Thank you for your advice.
Update: Even though the course image was uploaded and looked fine, for some reason clicking the 'crop' button enabled the save.
