Converting a MicroStation file to a n AutoCAD file.

I have a MicroStation file with level names, colors, and line styles and would like to convert it to an AutoCAD file that have different layer names, colors and line types. I'm using the "AttributeValueMapper" to determine "Source" and "Destination" values. I'm also using "AttributeManager" to set color and line types. An example of the "Destination" values in "V-TOPO-BRKL". It appears that it doesn't like the "-" since when I run the workbench it changes the Level-layer to the first name in the destination list. How van I resolve this?
