Public IMDb list appears private when viewed while signed out

Hi,

I am having an issue with one of my IMDb lists. The list is set to Public in my IMDb account, but when I open the list while signed out or in an incognito/private browser, IMDb says that it is a Private list.

List URL:
https://www.imdb.com/list/ls4117549539/

In my account, the list clearly shows the Public status. I have also tried viewing the list using a private/incognito browser to make sure this is not related to my login, but the problem remains.

Could an IMDb staff member please check whether this list has been incorrectly marked as private on IMDb's side and fix the visibility if necessary?

Thank you.
