Proscan logging question

I let Proscan log for quite a while and notice some TGID's that I don't have programmed that seems to have alot of hits on them.



A couple questions:



1.) How does my scanner find these TGID's when I don't have them programmed?

2.) What is the point of programming if my scanner finds these freq's/TGID I didn't program?

3.) Should I be programming these new TGID's that I found during logging back into my scanner for some reason?



I have a 996xt if it matters.



I have read the 'easier to read' manual and this stuff just isn't clicking.



Thanks in advance.
