Crystal Reports Select Case Default incorrectly returns blank

Message

     I'm grouping data by major product groups based on UDF_PRODUCT_CODE.  I want all ungrouped Product_Code's to return "Others"

I've used Default: "OTHERS" but the report is still showing blanks.  Anybody know why?

Here's my code (in Crystal Syntax):

Select {AR_InvoiceHistoryHeader.UDF_PRODUCT_CODE}
    Case "BENCH MART SR", "BENCH MART DELUXE", "BENCH MART PLAIN":
        "RETAIL"
    Case "MISCELLANEOUS", "SPORTING GOODS", "VINYL":
        "MISCELLANEOUS"
    Case "XA-210", "XA-300", "FIELD PRO", "PT - SERIES", "SF-23":
        "COMMERCIAL"
    Case "W TRUSS", "SUN STOPPER", "SUN SHADOW":
        "SHADE STRUCTURE"
    Case "HOBBY ACCESSORIES":
        "HOBBY"
    Case "FENCE- ON- A- BENCH":
        "DISPLAYS"
    Default:
        "OTHERS";
