None of those talkgroups are valid on the NJSP system - I would check your scanner's programming on the way you set up the system.
NJSP talkgroups start in 20000 range, most of them are in the 30000 range, the 40000 range is where you find most of the digital activity (including the DRJTBC), and then a bunch of outside agencies help round out the 50000 series talkgroups.
The low 4-digit talkgroups you are showing there have never been used on the system...
