SUE Extract Utilities from Graphics and Manhole appearance

Within a 3d file, I used the "extract utilities from graphics tool" from the SUE tools to extract 3d linestring for a Sanitary Forcemain. I see where this creates the links on the correct level for the forcemain, but I also notice that it creates a manhole at every end, of every segment along the inestring instead of just a pipe fitting symbol.  Is there a way to change this behavior?

In addition I used the node and link tools to model an existing sanitary sewer.  It seems to work for the most part, but the manholes don't appear to have bottoms, only a small linear feature extending to the lowest invert elevation. Can anyone tell me if I am missing a setting or if the feature setting is not correct?
