Modelbuilder loses track of Attributes

I am using an iterator (iterate feature selection) as the input to a series of tools.  One of the tools takes the input from the iterator, merges it with some other features and then builds polygons from the line features in the merged layer.  The output of the polygon building tool is a shapefile (polygon.shp) (or a file geodatabase feature class--I have tried both).  When I go to the next tool with the shape file as the input, the available attributes are the ones from the feature class used by the iterator, not the ones that were created in the shapefile.  If I add the shapefile (polygon.shp) into the table of contents and select it as the input to the next tool, the correct attributes are available.  Is this a know behavior?  Are there any known workarounds?
