Hello,

This is expected behaviour. It is a staff notice this hints that it is meant to be noticed by users that are logged in and not logged in. See more information below.

Post notices (staff notices)

In Discourse 2.3.0.beta4 we added a special call-out notice for new/returning users. Staff can now add custom call-outs above posts, which appear similar to the new user first post call-out. In latest Discourse, we made it so you can also use Markdown. [49] This notes can be added from the button (post admin actions) and Add Staff Notice.
