Vanishing posts in community on lemmy.world

I'm subscribed to https://lemmy.world/c/vermont, and when I view it I can usually either see "no posts" or only the most recent post.

But I go to the Lemmy.world URL at https://lemmy.world/c/vermont, instead of viewing through lemm.ee via: https://lemm.ee/c/vermont@lemmy.world?dataType=Post&page=1&sort=Hot

I can see all posts.
