Only recognizes one of multiple identicle string labels in report generation

[doczg]

I have input shape data in the form of part numbers assigned to various HVAC components, and some of these have multiple part numbers as separate strings.  The problem Im having is the report only recognizes the first part number and ignores all the others.  The goal is to easily generate a Bill of Materials for accurate part ordering, but if i have 3 parts assigned to a shape it doesnt help me if only one is recognized.

To clarify I have multiple "part#" string labels assigned to a single shape and only the first one on the list is sent to the report on excel.

Thanks
