Pro-file turning

Currently using Sherline lathe, EMC2 and dolphin cad/cam programs.
I have no problem creating a program that does linear cuts but when I make something that has a curve or rounded part, my issues begin.
I am trying to round over a piece of stock, simple. DO my initial face and my turning cuts but when I do a profile turn, it does a straight cut from the x0y0 to the end of the arc of the billet. Even running some of the rounded over examples included it gives me that sharp straight cut. Any ideas? I think I have the dolphin cad people stumped too.
thanks in advance.
Included is picture from EMC2 of my issues.

no picture, too big.
