Resetting the invoice template

I accidentally messed with the code on the invoice business template design.

Is it possible to reset it back to normal ?

In the custom design editor you can use the design selector to load a default design

I am referring to the default template. It needs to be reset.

Sorry, I don’t understand. Unless you modified the source code the default designs can’t be changed in the app, you can only use them as a starting point for a custom design.
