First of all, that is a nice setup and one I may be interested in duplicating in the future.
Secondly, I don't see anything wrong with your programming. With just those talkgroups in there and nothing else, they may just be "not talking" or using some other talkgroups that aren't identified. SDR would tell for sure.
The only way for certain talkgroups not to appear while others are assuming the same setup, is:
1) Greenwood PD / Leflore SO are "avoided" (which it isn't).
2) Greenwood PD / Leflore SO are not active on the site currently monitored.
3) Greenwood PD / Leflore SO are not active at all during the times that you are monitoring.
4) Greenwood PD / Leflore SO are using some other talkgroups
The only way to know more is to get the 436HP monitoring at the same time, with signal, and have it pick up Greenwood PD/Leflore SO talkgroups with the SDS100 silent on them. At the same exact time.
Try that or look into setting up an sdr on an old machine (cheap but a little more complicated).
