Nothing under unsigned in that screenshot should exist.

@Kegsay Do you know what's going on here?

No idea. I think the syncapi sets unsigned when updating the room state table or something. https://github.com/matrix-org/dendrite/blob/9f443317bc578e1897c7eab9b4911f952f39fdbc/syncapi/consumers/roomserver.go#L378 so perhaps we see the create event twice in the roomserver output stream?

This is almost certainly the case. We know that the roomserver can emit the same events multiple times.
