List appears on phone app, but not on desktop (web) version

I have list (named “2026”) i created before you forced me onto the new dashboard. this list is empty on Web, but not on ios app. How to I reconcile this? I want the content i added to list to be the same in both spots.

I also have lists from 2022, 2023, 2024, 2025 that are incorrect on web, but correct on ios.

Does the list contain episodes or seasons by chance?
