Adding movie to list leads to visibility issues

Hi,

The problem concerns the following list: https://www.imdb.com/list/ls071574809

Right after I added another movie to my list, I noticed the visibility issues (explained below) came back:

Once again my list is for some reason not publicly available, despite the "settings" indicating that the list should be visible for everyone (red circle "Public"): 

This issue is (likely) similar to: https://community-imdb.sprinklr.com/conversations/imdbcom/list-not-viewable-by-other-imdb-users-despite-being-public-set/62071bd56593b1779714cdce

Also, earlier this year, I made a post about exactly the same issue. Unfortunately, I cannot find that post anymore(?).

After posting, the issue was quickly fixed for me. Can this be done once more? And how can I prevent this, so that I do not have to encounter this problem again?

I would be happy if someone could fix it, thank you in advance! :)

Thank you and sorry for bothering you once again with my issue
