Cant see all posts in lemmy.world community

If I locally to go the lemmy.world community at https://lemmy.ca/c/[email protected] I only see posts that are 4 days old. However, going to the community externally at https://lemmy.world/c/lemmyworld lets me see all the posts. For example, the post https://lemmy.world/post/241226 is missing in lemmy.ca

I dont know if this is a bug or what.
