Family/Part Centerline Linestyle Mix-up

Drawing Extractions - Generate Centerlines

Has anyone ever seen a mix up with centerline linestyles upon extracting a file?  The image below shows an example of our firewall linestyles.  One diamond represents a 1HR wall and two diamonds represents a 2HR wall. 

If I start a new file, they extract fine.  On one problem file, when extracting the plan with generate centerlines in the cut plane tab, the linetypes are reversed - one diamond for 2HR and two diamonds for 1HR.  All I can think of that is different is I changed the family/part settings after the walls were created in the file.  I tried reapplying the part settings and the information shows everything is fine.  However, the extration result does not.
