Great Software - New User preparing for my first Walking with this in hand on my Galaxy S2

Is there any way, once a waypoint is created to either move or remove it when a mistake has happened?

Hi,
There is no way to change the location of a waypoint, so you won't be able to move it.
However you can remove/delete/edit them, depending on which kind of waypoint you are talking about.
Use the Displayed and focused landmarks side view (landmarks submenu button 4, see here) to see what is currently displayed on the map, and remove what you want.
Best regards
