Detach duplicate template spawn

I’ve got an app that controls a water tank level with a ping. Works great.
I want to use it as the base for another similar app with more valves and a more complex rule-set. I duplicated the original template but when I make additions to the second spawn they show up on the original app.

How do I detach the spawn?

Thanks in advance.
Jim-

I’d suggest that you provide more information, screenshots, details of your devices etc etc.
