Importing dgn with linestyles into ConceptStation

when I import a dgn file with linestyles (e.g. dashed) into ConceptStation they all appear as solid lines.  What am I doing wrong?  

Also, can I import dgn files with 3D linestyles into ConceptStation and expect them to look the same way the do in the dgn?

I am selecting the proper configuration information when selecting my dgn file to import.
