City shows 'contact.city' on Summary
I believe the 'Address Display Format' is not set properly in your system. Navigate to CiviCRM >> Administrator >> Localization >> Address Settings. Check values in 'Address Display Format' field. The contact.city should be inside open and closed curly braces eg {contact.city}. 

Default value of 'Address Display Format'

{contact.address_name}
{contact.street_address}
{contact.supplemental_address_1}
{contact.supplemental_address_2}
{contact.supplemental_address_3}
{contact.city}{, }{contact.state_province}{ }{contact.postal_code}
{contact.country}
