Persistent names of persistent entities in STEP export

I am not sure about the standard notes but these are attached when I select the option for export with names. I have attached the files. The file shown in left side of the figure is named as "sqrwn" and modified one is named as "sqrwn2".

The names are  52,62 etc. such as '52',#83.

For the case of left hand side

#99=ORIENTED_EDGE('52',*,*,#83,.F.);
#101=ORIENTED_EDGE('62',*,*,#100,.T.);
#103=ORIENTED_EDGE('57',*,*,#102,.T.);
#105=ORIENTED_EDGE('64',*,*,#104,.F.);
#106=EDGE_LOOP('61',(#99,#101,#103,#105));
#107=FACE_OUTER_BOUND('61',#106,.F.);

Whereas for the 2nd file

#147=ORIENTED_EDGE('100',*,*,#132,.F.);
#149=ORIENTED_EDGE('104',*,*,#148,.T.);
#151=ORIENTED_EDGE('66',*,*,#150,.F.);
#152=ORIENTED_EDGE('53',*,*,#103,.F.);
#153=ORIENTED_EDGE('107',*,*,#119,.T.);
#154=EDGE_LOOP('63',(#147,#149,#151,#152,#153));
#155=FACE_OUTER_BOUND('63',#154,.F.);

I have attached the files in CreoExport.zip. In the above figure, four fillets were added whereas the current case is with single fillet for simplicity.
