MIGO - NDR print indicator default to unchecked

Question

We would like to default the 'print' box in MIGO to always be unchecked when a user goes into the transaction.  There will be times when the user will check the box to print a label; however this will not be often.  Today, if a user checks the box, backs out of MIGO, then goes back into MIGO the box remains checked.  It's like it remembers whatever was set in that box previously.
We've tried playing with the user parameter of NDR being set to 'X' (capital), or being set to blank, but it's like the parameter is not being read at all.  The screen is only remembering what we did last when we re-execute the transaction.  We've also tried playing with the GET/SET parameters in SE51, program SAPLMIGO screen 0110 - but again no luck.
Am I missing something being set somewhere for the NDR parameter to be read?  Any tricks to get this to always default to unchecked?
Thank you for the suggestions.

I worked with ABAP'ers and it looks like this change was already in the enhancement section:
Program: LMIGOKH1
ENHANCEMENT-POINT HEADER_DEFAULTS_SET_02 SPOTS ES_SAPLMIGO.
Set print indicator
  GET PARAMETER ID 'NDR' FIELD ps_gohead-xnapr.
We also have this:
Program: LMIGOHG2
    CHECK lcl_migo_globals=>kernel->s_action-create = abap_true."       307284
     REPLACE
    SET PARAMETER ID 'NDR' FIELD gohead-xnapr.
The even more strange (frustrating) thing is that if we set a break point at the SET indicator in program LMIGOHG2, then the logic is picked up based on the user Parameter - not based on the last value that was entered.  However, if a breakpoint is set at the "get" section - it does not work.
I may be sending this one to SAP. Thank you for your suggestions.
