I have not spent a lot of time listening to this system - it's a bit far from me so I only get good copy during decent band openings.
I am far from a DSD+ expert, but if I understand correctly, all of these "0, 0000/00/00 0:00" entries are (I am told anyway) RADIO AFFILIATIONS - which to me means a radio was powered up on XYZ talkgroup. Why DSD+ doesn't log the date/time that event occurred, I do not know.
You can see that the only group I have actually logged traffic is TG 65122. This is a patch TG of some type/flavor.
