Send SMS option Store In Messaging App is unchecked, but the SMS still shows up in messaging app

I have a basic profile for replying location:

Look at received texts

-> Get Location v2 (Enable location if needed)

-> Send SMS (send to %smsrf; message is map url; Store in messaging app is unchecked)

The sent sms still shows up in the default messages app (Google Messages).  Does the same thing on a Pixel and Pixel 3.

Are there any suggestions as to how to stop the sent message from showing up in the messaging app?

Thanks,
