Fortunately this issue is pretty quick to resolve. Just open your template, place a new component or grid and renumber the Mark/Name parameter so that it has the number just before the one you want your user to get with the template when they get started. This works fine for numbers but I'm not sure what to do about letters. If you want the grid to start with A...what comes before A? I've tried to get it to start with A again...but no joy.
I made a short video that shows what I'm writing about.
