Hi tucsonspeedway,
Thanks for reaching out!
Sorry about this issue. We did have a bug where the status change on the attendee page wouldn’t be reflected immediately. The changes should be visible though after some minutes.
This was fixed in our latest release of TEC 4.6.18. In case you haven’t yet done so, please update your plugins (after creating a full backup of your site and files, just to be sure), and check if that solves the issue.
Let me know.
Cheers,
Andras
