Why are my contacts showing up as numbers instead of names?

Recently, my contacts show up as numbers instead of names. I've tried numerous fixes for this and can't seem to get the issue resolved for longer than a day.

I've tried this fix:

Settings, Contacts, Accounts

in each account turn off Contacts

Delete from phone? Yes.

Restart the phone

Back in settings again turn on the correct account for contacts

It did not work. I've changed the region in my settings and shut down my phone and turned it back on and changed the region back. That didn't work either. I've checked for software updates and those are all up to date. Sometimes it will fix it for a few hours or once it lasted for a day, but then they always go back to numbers. It's very frustrating since this is a new phone and I'm constantly trying to fix this issue. Please someone help!!
