Depending on the phones you may receive the SMS as true SMS because either the sender or receiver doesn't support RCS.
Looking at your macro, first off you left a phone number in there, I assume that's yours because from what you're describing it doesn't update.
If you are using the notification trigger {sms_number} won't work. However if it doesn't update when receiving a true SMS, that's weird... Make sure all the permissions related to SMS and phone calls are enabled.
Also check both the troubleshooting section of the app and the system log (green tile on home screen).
