[Dxbase] HF statistics show up

[ILYA ZOZIN 4Z1UF]

 Looking at Output->HF statistics-> whatever.
While clicking on the any of the right side choices (Worked/not confirmed
etc) I'm getting the list of ALL worked/not confirmed entities, but not per
band, even after choosing specific band/mode combination and "computing
list"
For example, I see that I do not have zone 3 confirmed on 40M phone  for
WAZ. Clicking on it I'm getting the list of all stations from zone #3 that I
ever worked  (> 100) and have to find among them single (may be more)
40M/phone contact that I have. 
Same story with countries, states etc. which is even worse.
 Is it possible to be pinpointed to the only band/mode that I'm interesting
in?
