[Dx4win] Confusion over "checked" awards flags

[Floyd Sense]

Given enough time, I might be able to figure this out myself, but I'm sure
one of you has already been through this so will just ask  in order to save
some time.  I converted to DX4WIN about 18 months back and imported all my
log data from the previous logging program (running 5.03 now).  When I did
that, I went through the QSOs that had already been credited for my DXCC and
marked them all "Checked" in the Mixed DXCC award flags.  So, when I look at
the DXCC summary report, the right number of countries appear as Checked.

Now it's time to submit for 5BDXCC and I attempted to prepare a submission,
but DX4WIN tells me that it won't include 4 of the bands because I'm already
credited for 100 countries on those bands, which is incorrect.  So, I look
at the DXCC listing report and take a look at the line for 3B6.  It shows a
"C" for the bands 30 through 10, because a QSO marked confirmed=Y exists
with 3B6 on each of those bands.  Only one of those QSOs has the DXCC Mixed
awards flagged set to "Chkd".  It appears to me that DX4WIN is counting all
such QSOs as "Checked" even though they have not been.

Can someone tell me what I'm missing?  All QSOs that have the DXCC Mixed
awards flag set to Chkd show up as a "*" in the listing, and I assumed that
DX4WIN would only count THOSE QSOs as already checked.

All ideas appreciated!
