Multiple addresses in Linked Contacts

I use Gmail for my email platform on my iPhone. I have all of my contacts in iCloud, as well as my Gmail account. To prevent duplicate contacts, I have them all "linked". I recently noticed that some of my contacts show the same address twice while others only show one address. I checked to see why the difference, and I can't figure it out. These contacts have everything set up the same - linked accounts from iCloud and Gmail, addresses are listed in both contacts, addresses are the same. Only difference is some show 1 address and some show 2 (even though address is identical). I have tried to "unlink" them and then "link" again but that doesn't work.

Any suggestions?

Thanks!
