Some fields are not included on the email confirmation.

The confirmation email for https://form.jotform.com/70947148938168 looks like this when I'm creating it:

but when the email is sent it looks like this:

The email was copy and pasted from another form, so I suspect that is the problem, but everything looks fine when I'm editing it, so I'm not sure how to fix it.

Your email notification is setup correctly. The reason you are seeing those boxes (Name of Commercial Interest, Who has the relationship etc..) are because of the configurable list widget. That is how the widget is rendered in the email body.

If information is not included, please delete your email notification and add it again by following this guide https://www.jotform.com/help/25-Setting-up-Email-Notifications.

Your autoresponder emails are conditionally sent, one of the autoresponders doesn't have any text in the body of the email:

I understand that the emails are conditionally sent, that is why the {form_title} header on the the email without any text is a different color, so it's obvious that it's not the same email.

I solved this on my own by adding a new row that shows up when the email is sent, but it is frustrating that I still don't know why it is happening, so there's no way to prevent the issue in the future.

If the formatting was copied directly from the text of another email, it could have been inserted differently in the code of the new notification.  Copying the full source code instead of just the text of the notification would ensure that the exact same code is used and inserted in the same manner:
