My Public Imdb List is Still Showing as Private to Others

Hi, I have set my list to "Public", but when I open it from other accounts or incognito mode, it still shows as "Private". I’ve checked all the settings, saved them correctly, and removed any external links. Here is the list URL: https://www.imdb.com/list/ls596222322 Can you please check if there’s a system issue? Thank you!
