SW to STEP - "any" string is added to component names

Below is a snippet from a test STEP file I exported out ofSW. For some reason, it is writing these 'ANY' strings into theSTEP data, and when ProE imports this, the filename becomessolidworks_2007_cylinder1_any.prt.1 which is a problem. I don't seethis in the STEP file from other cad systems. I will investigatethe ProE side, but does anyone by chance know how to prevent orcontrol this on the SW side?

#447 = PRODUCT_DEFINITION_FORMATION_WITH_SPECIFIED_SOURCE ( 'ANY','', #453, .NOT_KNOWN. ) ;
#448 = PRODUCT_DEFINITION ( 'UNKNOWN', '', #447, #449 ) ;
#449 = PRODUCT_DEFINITION_CONTEXT ( 'detailed design', #451,'design' ) ;
#450 = APPLICATION_PROTOCOL_DEFINITION ( 'draft internationalstandard', 'automotive_design', 1998, #451 ) ;
#451 = APPLICATION_CONTEXT ( 'automotive_design' ) ;
#452 = SHAPE_DEFINITION_REPRESENTATION ( #445, #377 ) ;
#453 = PRODUCT ( 'solidworks_2007_cylinder1','solidworks_2007_cylinder1', '', ( #454 ) ) ;
