The email is dynamically created based on the form element names. Try doing the find and replace on that contact.php page and you will see what I mean.
I see the form element: name="Your_Contact_Information_group_Contact_Reason"
If you did a find and replace on the page and replaced all occurrences of: Your_Contact_Information_group_Contact_Reason
with: Contact_Reason
Then I think the email would look how you want it.
