OPIM incorrectly separating material in BOM after inline instrument

If an inline component from the instrument module (i.e. orifice flange set) is inserted in a line, OPIM will separate the material after the orifice flange from other identical material.  This material should be grouped as my BOM grouping is set to PARTID in the REPORT.DEF file.  Please see report.def file and iso attached.
