Hi Andy,
Thanks for getting in touch.
I’m really sorry about this. We have recently discovered this bug. It is already on file and waiting for a developer to be assigned to it.
Note: If you create a new event and add 2 organizers, then reorder them before saving, that order gets saved. So this appears to only occur when updating an existing post.
I am going to set the status of this ticket to “pending fix” and we will update it once the fix is released. If you have any new questions or issues please create a new ticket and we’ll be happy to help.
Thanks and cheers,
Andras
