I am having Springsharp 3.0b1 Beta troubles

I am seeing the sort of problems that exist with Springsharp 3.0b1 Beta. They seem to center around the "Speed, Range, and Power" page and what shows up in the "Performance" and "Report" pages. I am trying to do a BB-27 Michigan design (photo from this New York Shipbuilding site), and odd things are happening. The "Composite Strength" is bouncing around with what I would expect to be only marginally related changes. The Michigan is interesting to me because it was very small, but had 8-12in guns, with superfiring turrets. It is the earliest example of a more modern layout. The Dreadnought was still using a pre-Dreadnought layout, in may ways (oddly enough). This is the Springsharp report:
