Merge Contact Lists - Repost

Hey, I'm reposting this from an earlier subscriber question. The most relevant response with not relevant at all - so I'm reposting to see if anyone can assist. Thanks for your time!

I currently have multiple contact lists on my iPhone. I would like to have my "All Contacts" synced to my "All iCloud", so I can have the latter one on my mac as well. Right now my "Messages" app is not showing names, only numbers. I think the reason is because by "Contacts" is not synced properly with my phone.

Any suggestions?
