Contact email is displayed as None in detail view

[rodvand]

NetBox version

v3.1.0

Python version

3.8

Steps to Reproduce

1. Create a Contact with name "Contacto" and email "contacto@emailo.com"

Expected Behavior

The detailed view should display the Contact's email address.

Observed Behavior

When accessing the contact's detailed view the email address is displayed as None. If you edit the Contact and add a phone number for example, both the email and phone number displays in the detailed view.

The Contact's email address is displayed in the list view (/tenancy/contacts/).
