[DXBase] DXCC Prefix Callsign Mapping Problem

I switched from LOGPlus 3.55b to DXBase 2002 v1.01 a few months ago.  It has been a lot of work transferring 75,000 QSOs from one program to another!  One persist problem is that my DXCC totals (including band countries and related totals) are ALL lower on DXBase reports even though I have meticulously tracked all of the 'problem' prefixes over the years and carefully entered this data into DX Base: 3D2, 4U, KC6, VP8, ZK1, et al.

I have made about 100 entries in the DXBase Prefix Callsign Mapping Table, assigning the correct DXCC Prefix to each callsign according the QSL card and other information known to be correct.  However, DX Base continues to count these QSOs under their old, default DXCC Prefixes apparently without regard to the data in the Prefix Callsign Mapping Table.

It does not matter how many times I run Initialize Tables, the old -- incorrect -- DXCC Prefix data is still associated with these QSOs.  A few examples:

CALL         DXBASE DEFAULT PREFIX      CORRECT PREFIX

4U/F6IRF     YK                         XU
4U/N6BFM     YK                         YI
4U/T93A      YK                         HH
KA2AM        K                          JA
KA2GS        K                          JA
TO2T         F                          FG
VI0ANT       VK                         KC4
VP8CBE       VP8                        VP8H 
VP8CKC       VP8                        VP8O 
VP8SGP       VP8                        VP8G
ZK1UVO       ZK1/S                      ZK1/N
ZK1VDX       ZK1/S                      ZK1/N
ZK1VTK       ZK1/S                      ZK1/N 
ZX0A         PY0F                       KC4
etc...

Curiously, if I enter a new QSO into DX Base with any of above callsigns the DXCC Prefix information seems to be correct on this new test QSO.  However, the old QSOs under such callsigns cataloged in DX Base continue to have the old, incorrect DXCC Prefix data.

Help!  What am I doing wrong?  I have read the DX Base Help file backwards and forwards on this topic.
