Lost a bunch of posts on some communities I mod

Hey all,

Have any of you seen this? I mod a couple of communities which have a number of posts each. They're not huge, but one had something like 16 posts and the other had 17.

The latter one is down to showing just 5 posts ( https://lemm.ee/c/whatcouldgowrong )

What happened? And can I get those back somehow?
