Service Log App question(sample)

I Am new to AppSheet and can not seem to figure out how to edit what appears on the job details screen or the Customer screen on the Service Log Sample App.
I am trying to add a 3rd line of info to the customers screen and figure out where/how to change what shows in the Details screen.

Any help is appreciated!
Thank You!

Hi @Hawk Did you try clicking on the pencil icon and editing the entry?
Also have you copied the app to your own account?
