dspobjd problem with *libl, *usrlibl

At V5R2, cume 04077 applied, I am not getting proper results from DSPOBJD 
command
in both command line and outfile results (or else I'm really blind today).
My *libl has multiple libs with QMNUSRC file (here of a few from WRKF 
FILE(*LIBL/QMNUSRC) )
QMNUSRC     QGPL        PF
QMNUSRC     CHG402      PF
QMNUSRC     #LIB402     PF
QMNUSRC     AP402       PF
QMNUSRC     AR402MOD    PF
QMNUSRC     AR402       PF

DSPOBJD OBJ(*LIBL/QMNUSRC) OBJTYPE(*FILE) says only 1 library in *libl has 
object!
                      Display Object Description - Basic                       
                                                                Library 1 of 1 
Library  . . . . . . :   QGPL            Library ASP device . :   *SYSBAS      
Opt  Object      Type      Attribute               Size  Text                  
     QMNUSRC     *FILE     PF                      8192  Default source file f 


but this works with same libl: DSPOBJD OBJ(ap402/QMNUSRC) OBJTYPE(*FILE) 
 Library  . . . . . . :   AP402           Library ASP device . :   *SYSBAS   
 Opt  Object      Type      Attribute               Size  Text               
      QMNUSRC     *FILE     PF                   1196032            

This is breaking my xref programs.
Have searched ptfs for v5r2 and see no match. 
Anyone ideas? Unfortunately this is a "managed" system
and doubtful I can make a support call.
