Why do WhatsApp Chats show phone numbers instead of names?

[Windows Central Question]

I have WhatsApp client version 2.16.64 installed on my Lumia 535 double SIM with Windows Phone 10, version 1511. For some days now, under "Chats", the full phone numbers are shown instead of corresponding names. That makes it difficult to attribute chats to the right person. Additionally, I can't start a new chat since only four contacts (out of several dozen contacts) are listed in "Favourites".

I have heard of other persons having this issue, but so far, I did not find a solution, WhatsApp support seems to be working with computerized answers that don't make much sense...

Just fixed this on my Android phone. Uninstalled Google Duo, and voila, all the names started showing up.
