Yes I'll be logging the issue with the Complex Transition between any Element and Arc with the development team.
I didn't explain myself correctly, when I said similar I was referring to your alignment alignment style, i.e straight - curve - curve - curve with transitions on the curves.
You can use the Reverse Spiral Arc to/from Element and Spiral Line to/from Element tools to create an OpenRoads alignment the same as your MX Alignment.
