Carveco Maker simulation not showing bowl bit radius


I just received a new SpeTool Bowl and Tray bit 1/4" radius x 3/4" Dia x 1/4 Shank.

For some reason I cannot figure out how to run a simple groove that will have curved edges on the bottom. Maybe it is doing it but its not showing it in the simulation at least. The funny thing is I can do a simple groove in Vetric but its only the trial edition. I have uploaded the Vetric image. When I create the same thing in Carveco the corners are all sharp. Any help would be greatly appreciated.
