Arc between Arcs - can't get proper solution

Hi,

I'm using Civil geometry tools to recreate horizontal alignment designed in MX native tools. I can't get proper solution when using "Arc between Arcs" with Double spiral option in one of my transitions. It works fine only with Single spiral option. Tried in PowerInRoads .722 and MX .722 without success. The video below presents the issue I have. Does anyone share similar problem?

Thanks, Krzysztof
