What's up with communities coming up as deleted on lemmy.world?

Many communities come up as deleted for me when I open them, although I can access them from my local instance. All of them are in lemmy.world. Some examples would be

1. lemmy.world/c/syncforlemmy
2. lemmy.world/c/android
3. lemmy.world/c/reddit
4. lemmy.world/c/fuckcars

Is it a me problem or is everyone else also facing this?

Edit: It's working now after deleting cookies and site data for lemmy.world.
