slot number changes with REF DES assignment

In DxDesigner/PADS 9.2 I've got a hetero component with 4 parts (HETERO 74LVC125,(74LVC125P))--I don't know what 'hetero type' this is.

 

I assign the PKG_GRP value =1 for all four instances on my schematic, and assign slot numbers 1-4 to each of the 4 instances.  The instance in slot 1 is symbol 74LVC125P, the other three are symbol 74LVC125.  When I run PCB Interface/Assign REFDES it assigns an identical REFDES to all four instances (as expected), but it changes the slot number.  If I go back and change the slot numbers, it resets the REF DES.

 

What am I doing wrong?
