List set to public shows as private to others.

I have lists I’ve made that I set to public to share with friends, yet they always show as private and therefore cannot be viewed by others. I have this issue with every list (yes, I quadruple checked. They’re all set to public.) Here’s the most recent example: https://www.imdb.com/list/ls547812797?ref_=ext_shr_lnk I saw another similar post about the same issue and the response said to not include links in the description to avoid the problem in the future, but I don’t have any links on any of my lists so that’s not helpful at all. Please help.
