comma(,) is getting added in the location extension address in Google Adwords when deploy a request without streetAddress2

In Google Adwords location extension street address comma(,) is getting added if cpp doesn't have optional street address i.e, streetAddress2, streetAddress3, streetAddress4.

Expected behavior: Should not add comma(,) in the address if optional streetadress is not mentioned in cpp and its not looks good when address displayed in Google.
