Hi Andrew, I am not seeing this on my iPhone 6S running the latest iOS release of iOS 11. It sounds like the Messages app is not properly coordinating with the Contacts app. I would go into your iCloud settings and verify that Contacts is enabled and also verify that some of these specific contacts are displaying properly in the Contacts app. If things look normal when checking these items, first thing to always do is restart your iPhone. If you've done that already, or if nothing improves, try turning off Contacts in iCloud then turning it back on. I've found that the best thing to do when turning it off, is to turn it off, then back out of Settings, then re-open Settings and the iCloud pane and to finally re-enable syncing of your contacts.
HTH. Later...

After I’ve updated to High Sierra and to iOS 11, conversations are not always threaded at all and the sender name is missing, replaced by their phone number. This is a bit of a nuisance. I’ve searched for a setting to adjust but I can’t find it. Might it be a bug? The strange thing is that if I compose a message first and choose a particular contact from Contacts, then the message appears with the name of the person I have sent to but if they reply to my message, their reply is not a part of the thread but appears separately and it is their telephone number that appears in the list of messages so you can’t tell who the message is from unless you read it. I’m also having trouble deleting messages. When I choose to delete a message via the action menu, Messages app still reports this message. Nor does the status of the message changes when I’ve read it. Is this something you are noticing as well? Andrew -- The following information is important for all members of the Mac Visionaries list.
