Hanouts Contacts Problem topic

Guys, a strange Hangouts problem - When I add new contacts, if I receive a Hangouts message from them, in the Hangouts list of messages it only shows their mobile number - not their contact name. The strange thing is that in Notifications and when I go into that contacts message it actually shows their name.

So, in short - I have a contact stored with their name and number. If I receive a Hangout message from that person it DOESN'T show their name in the Hangout list of messages. BUT it does show their name once I open that message. It also shows their name in Notifications!

Strange!!!
