Why are there erroneous dates on the middle column view for Sent mailbox ?

Hi! I'm trying to move email into folders to export mboxes and in order to select the precise emails that I want to move, I sort the box where they are located by date (either "oldest" or "newest" in the View > Sort by in the Apple Mail menu bar.

When I do so, I see the a lot (meaning over 50) of my emails have the wrong year (2022) and can be verified that they are wrong when you double click to open the email and then see the correct entire date (say actually 2016 for year).

I assume there's an indexing issue, but in Apple Mail Ventura, how to I fix this? I can't find how to rebuild the box where the orignal emails are located. If there's another reason, I'm all eyes for instructions on how to fix this error.

This may also be occurring for other types of mailboxes, but I haven't the time to confirm.

Well you can rebuild mailboxes— and see if it sorts your issue.
