[LogPlus] "Clearing" Bad Data ... 5BWAZ

[Billy Cox]

OK ... something went wrong with recent IMPORTs from
Writelog to LOGPlus ... I'll look into that next ... here's how
I noticed the problems.
 
First ... and my present query ... when I was posting some QSO
and checking my WAZ totals I noticed that my 160m numbers
seems high, so looked closer and found USA QSOs from
the ARRL 160m Contest to be shown as "Zone 17, and 18."

And I see similar problems on 80m too ... 
 
I went in and corrected the actual Zones for those QSOs data ... 
but now can't figure out how to "clear" the bogus information from
the zone totals ?  (Tried re-indexing, deleting the *.NSX, etc.)
 
 Ideas here please ?
 
 TU !
