Remote Community out of Sync with Beehaw federation of it

There are some communites I'm seeing in which the Beehaw page hasn't been updated for a couple of weeks while the actual community page on their own home has activity recently. Example: https://beehaw.org/c/selfhosted@lemmy.world/data_type/Post/sort/Active/page/1 https://lemmy.world/c/selfhosted

Our page shows the last activity 18 days ago but if you jump over there it shows a new topic only an hour ago. I don't believe they have been defederated or anything since we can still browse it at all. Any idea what's going on here?
