I think the Expression map editor is not behaving right regarding the Length field. Whenever I type a value there, it gets stored in the Transpose value (divided by 100) as soon as I hit OK or switch back and forth to another expression map. That is, if I type 200, the transpose value becomes 2, if I type 300, the transpose value becomes 3, etc. I enclose a video to show what I mean.
