"Only visible to members of group: staff" false message

[Moin]

There will be a fix soon

What does "only visible to members of group:" tell me?

I took this screenshots while I was not logged in. So I was definitly not in that group, but still able to see this posts. It’s the same for all the replies. So since the posts are visible even to anonymous users, why is this notice shown, if you click the post date? [_20220413_132039] [_20220413_132058]
