Can't see anything up with the vectors so it's probably a bug in the gadget. The Vectric Chamfer gadget that it is based on doesn't appear to do that. The author of this gadget hasn't been on the forum for quite a while.
However you can do what you're doing using the moulding toolpath that is built into Aspire so no need to use a 3rd party gadget. Also I would just create and toolpath one of those and then use the Array Copy Toolpath tool to duplicate the toolpaths for the others.
