WPX-missing QSL Logbook view?

[DG7RO]

aehmm..... small problem:
in my log i have something like this:
  jw9jka 17m@date1 - no qsl send or received
  jw9jka 17m@date2-later - qsl send and received

Now my select statement selects the first qso of 17m as this is not confirmed and no qsl is sent.
But later I got a QSL card  and the prefix JW9 is confirmed.

How could this be included in the selection-generator
