The Load Plan dialog box is confusing

[JMason]

When I load a previously saved plan a "Load Plan" dialog box pops up containing confusing text.  It says: "Do you want to load and overwrite all plan settings from this plan or only destinations"  The choice buttons are labeled: "Destinations only" and "All Plan Settings"

I cannot find a explanation of exactly what happens when you select each of the buttons.  I don't want to ruin a plan that I've put some time into. 

Thanks, Jim

I just started using the app (on iPhone) and I am getting the same confusing dialog when I try to load a saved plan. Selecting either option appears to do nothing and no route is loaded. How do I load a saved route?
