Letting user change just some fields wipes out unchanged field

I’m working on a customer self-service page. When the user updates, for example, their phone number, the phone number is updated but the data they did not change is overwritten to be blank. I’m probably not using the right search terms, but I can’t find anything in the forum on how to leave the old data as-is, while letting the user update only some fields. Any help would be appreciated.!

Okay, I figured it out with the help of this tutorial:
Auto Binding in Bubble.Is (What It Is & How to Set It Up)

I just removed the “When Text Save is Clicked” workflow, enabled auto-binding in each input’s property editor, and updated Settings > User > Privacy > Allow auto-binding. It’s working great now.
