How to shut off vibrate after Oreo upgrade?

[Android Central Question]

Just did the Oreo upgrade on my phone. Now its vibrating when i get ANY message. I'm trying to follow the steps to turn off the vibration, but once i go to Apps & Notifications > Messages > App Notifications instead of giving me a default option it is listing every single conversation I have on my phone. What's going on?

Without knowing the phone, all I can do is to move this to the general Oreo forum.
