Inbound messages does not substitute subject and from

Each row in the overview page shows this:

[your-subject] [your-name] <[your-email]> Contact Form 7 / Request a quote 1 min ago

My form does not define your-subject, your-name, or your-email, so there is nothing to substitute. On the details page all my emailed info is displayed correctly. Why not use the info gathered into the address book for the fields in the overview page, so that in cases where forms don’t use those hard-coded fields the list still makes sense?
