Labels in Crystal Reports v 14. Sage 300 ERP 2014 PU 3

I created a label report with a dynamic parameter for the user to select the range of items to print, and am trying to run it. It runs - but only with a fraction of the items in the range list (there are 30,000 items). I did the List of Values fix in the registry but to no avail.  

I have a feeling I am missing something altogether.  Any ideas would be appreciated.

Thanks
