MacOS – Smart Mailbox Folder not displaying mail

macosmail.appsmart-folders

I've got two smart mailboxes named NEW eric@ and NEW ericgorr@ which contain only new message for corresponding email accounts. I have placed these two smart mailboxes into a smart mailbox folder named Personal. When I select Personal, I see that it will show me the new messages contained in the smart mailboxes it contains as shown in the image:

So far, so good. However, I created another smart mailbox folder called Personal 2. When I move the smart mailbox NEW eric@ into Personal 2 and select Personal 2, no messages are displayed as shown in the image:
