Disk Usage fails to show mailboxes

Here Mail > Mailboxes shows two, but Status > Disk Usage , Disk Usage by Mailbox says

There are no mailboxes on this account.

Anyone else get this. Any ideas what’s up?

It says that in my panel, too. My mailboxes tab shows three mailboxes, but since they’re shell/ftp users, the disk usage for those users’ mailboxes seems to be rolled into “disk usage by user” instead.

Is that the case with you, or do you have mxxxxxxx mailboxes that aren’t showing up there?

It is the case with me. That “By User” includes the users’ mailboxes is expected. That “By Mailbox” doesn’t looks like a bug.
