After the September update (GXGB) my phone app is not using default apps

[rvcjew]

When I am in a call then end the call and hit the message icon to send a sms (rcs) it brings up the picker for what app to use instead of going direct to Google messages as set in settings/apps/default apps/sms. If I pick messages then hit always it remembers but only for that one contact. Every single contact I try to text after a call will prompt this picker.

This has got to be a bug right?

Phone app is version 15.1.98
