Several Members are stuck in what looks like a "loading" state. You can see their name, but no thumbnail generates for their avatar, and there is no pencil icon to edit their roles/notes/kick/ban.

Attachments:

(1) screenshot of group member list from VRChat website. Several members are missing thumbnails, and cannot be edited. (Blurred names and avatar previews for unaffected members). Affected members are boxed in red.
