Unable to disable notification banners after Catalina upgrade

I noticed after I upgraded my Catalina ios to 10.15.6 I haven't been able to make notification changes for certain applications (for both Apple applications and other applications that I've downloaded).

The notification I primarily want to disable are the alert banners for Messenger, because they're distracting. Within the notification setting for Messenger, banners is selected by default, and all the other options are grayed out, and thats where I'm unable to change anything. I'm not even able to disable all notifications entirely

Again, this applies to a number of different applications (messages, maps, excel, outlook, chrome). All the settings are set to enable Banner alerts, and I'm unable to change anything else to what is grayed out.

There's only a few applications where this doesn't apply (calendar, wallet, slack), and I'm able to make whatever changes I'd like

Am I overlooking something here? It's driving me crazy!

Any solutions?
