Wrong List Item Selection Or flipped Curves? :/

Ok I problem here, I have a brep and i  Project on it like 30 curves, then i ofset this curves and create a surface from this curves, resulting the image 1.

 Now I Want to select   the diferent groups because the geometry is too big for cuting in laser machine plotter, so  I Want to separate this 5 segments, If you see the image 2.

I select the item number 3 that is in the midle and its all fine, but if u watch the image 3 when i select the Item 2 for example tooks segments for randomly :(.

 Its like the curves are not in the same direction, i tried to flip them but no results, I tested the curve direction and it seems all ok. Look at this:

This is killing me T_T... any commentaries...
