If you push "edit" on my version, it will open up the patcher object, which is reffered to as a subpatch. There you can see how everything is set up.
If you push "edit" on the one you pulled from the factory library you will see that it is empty. Nothing is loaded into that one. If you want you can add you own stuff to it, but by default it is empty.
When using a patch/patcher you should really not edit the code in the code editor, you should use the edit button to open the subpatch so you can see the objects loaded in the subpatch.
Anyway, you should probably check some of the user guides or check some video on Youtube to get familiar with the editor. I think you can almost find videos about anything or esle there is lots of help in the user guides too Doing that will make all this easier to understand.
