Rob,
Are you saying that you are saving other talkgroup ID's ? If so, when you do, it saves them under service type "Custom 1". You'll have to go back and edit the service type to "Corrections".
The other option is to leave "Custom 1" enabled and you'll always hear the new stuff that you discover and save, allowing you time to change the service type at a later date
Keep in mind, if you don't ever change it and "Custom 1" is always on, you will hear that activity, even when you are trying to listen to something else. So it is best to change the service type to the correct service type as soon as possible, for the service type function to work well for you.
