[Dx4win] confused about log file

[George]

I am confused about how DX4WIN handles a log file that I made and currently
have loaded with only the contacts starting with 01/2015. The log file with
only 2015 contacts are in and fine but DX4WIN is still keying on my log from
the very beginning of 2002 for spot colors/numbers?
 I want DX4WIN to only key on the log I have loaded which are Q's from
01/2015 to current? The "spot" and "other" contacts are still keying on my
log from 2002.
How do I tell DX4WIN to use the current loaded log which has Q's starting
from 2015 to populate the spot window and the others window not the log file
from 2002 to present?
I'm trying to work DXCC starting with 2015 which is the log I have loaded.
Thanks.
