Unless you have gone for extremely high AoA or very low drag the flap will usually extend as far back as possible to get the greatest chord. You will notice that almost any front wing will use as much of the allowed height, width and depth as possible.
You can see how much space the front wing has here. It goes to the back of the endplate, your old wing appears to end where the above wing's middle flap ends.
