Now when you do a database update, it does NOT UPDATE favorite lists as they are user generated.
If you made your favorite lists BEFORE the database update could explain your dilemma, we made quite a few updates and additions for Wexford in last few years.
I see you mentioned about updating the database. Yes in these zipcode scanners databases are several years old. I can attest to that as Ive seen a few brand new sds100's, a 436, home patrol 2 in last few weeks and the databases were anywhere from 5 - 9(the SDS100) years old!
I would try using the full database for now as I'm sure it would work that way and then you can re-check your favorite list(s).
Probably easiest way to do a favorite list is in sentinel -> Edit, then Add channels on range.
Make sure while scanning, its going through the four unique frequency towers in Wexford, you would see these in the middle-lower part of the display-
Manton
Mesick 1
Wellston
Boon
Osceola - Leroy
Missaukee - Falmouth
General rule of thumb with a rod antenna is you can pickup your county and the surrounding counties, but it all depends on your location and each counties tower location. 850's MHZ... well as you go higher in frequency, the distance they can be picked up drops off.

Just an FYI, I cant help mentioning, unless you plan on traveling a lot with it in the lower 1/2 of the lower peninsula, where all the simulcast- multiple tower, same frequency counties are or other states, hate to say it, you way over bought$.
The selling point of the SDS scanners is to work in simulcast counties that Wexford, Osceola and Missaukee are not, as mentioned above they are unique frequencies for each tower.
A lesser priced 436HP zipcode scanner, WS1040 or a 325P2 - both user programmed would work.
