Federation weirdness between beehaw and aussie.zone

So along with my beehaw account I have an account on aussie.zone (which is still federating with beehaw as well as the reverse as far as I'm aware).

Anyway I opened that account secondarily so I could access a community thats on a instance beehaw doesn't federate with and so I subscribed to all the beehaw communities I had previously used and fifured I could just use the one for now.

Since then I have noticed a few federation werdnesses in relation to the beehaw communities subscribed to with that aussie.zone account and I'm a bit confused. Maybe someone can explain it to me.

With the beehaw community 'Humanities', from my aussie.zone account the community is empty. I see no posts or comments except for one post I made myself (and that post I can see from my beehaw account so it did get through).

With the beehaw 'entertainment' community, I made a post from my aussie.zone account and again the post went through as people on beehaw have upvoted and commented on the post, but none of the comments or upvotes are visible from my aussie.zone account.

It seems all very weird to me.
