Some e-mails for a few contacts don't get recorded in Journal

[ABQSteve]

I have 2 contacts out of several hundred, whose e-mails never get recorded in
my journal. I've checked their e-mail address in the incoming e-mails, and
it matches my contact. Their names are checked in the "record e-mail from
the following contact" in the journal option. I know how to use this feature
but, for some reason, these two contact's e-mails don't get recorded. Has
anyone ever had this problem, and does anyone know a solution?

Thanks,

Steve
