While the images shows the e-mails causing the bug from PWE, there are other e-mails which fails to show up the original date, and instead showing the sync date as the mail date. I added them as examples too.

Also, this bug only happens on Zoho Mail, I did not have the same issue on my Gmail and Hotmail.
