I'm having trouble editing a WhatsApp contacts' name. I have this contact saved in my contacts list with the desired name, but WhatsApp just doesn't want to use that name apparently. I can even see the WhatsApp "voice call", etc. options from the contacts screen in my contacts app. If I'm on the contact page in WhatsApp, clicking the dropdown menu "edit" or "view in address book" simply doesn't work, so I think this is some kind of sync problem.
In my Contacts app on Nexus 5X, when I select "All Contacts", there's only one version of this specific contact, under the correct name, so I don't think there's a duplicate with the wrong name unless WhatsApp has somehow hidden this duplicate.
I feel like I've tried everything you can possibly try by googling; deleting the contact, playing around with WhatsApp permissions, etc.
Any insight is very appreciated.
(How it seems to me: WhatsApp has some kind of hidden contact list somewhere that I can't view/edit, from which it keeps syncing the wrong contact name)
