Error in spiral between same sense curves

After creating a spiral-curve-spiral between 2 curves, I noticed the curvature of the spiral was inconsistent. A report confirmed this.
Where the spiral should have been between 2 clockwise curves, it was created as if it was between a clockwise and a counter-clockwise curve.
The images below show the wrong and the correct results, the selection from the report confirms that the spiral is calculated as if it connects to a curve in the opposite direction.
Does anyone know how to do prevent this from happening using the spiral-curve spiral option?
