Is there a reason on Hangouts why some people appear once and you can select hangouts or SMS from the drop down menu at the top (how it's supposed to work), while others appear twice, with one being hangouts and one being SMS and the drop down menu has no second option. They both are in my contacts with a phone number and a gmail address with no other differences between them.
I can't find anyone with the same problem as all the search results are just complaining about it not being all within one stream like iMessages. But my problem is one step above that since they appear as two different contacts entirely so it's even more of a hassle to keep up with things.
