What am I missing here. Two #10 AWG wires to feed a 100 amp panel isn’t nearly enough amperage.

I agree, looks like an excessive gap at areas around the panel.
I don’t think you are missing anything.
Yeah, not only undersized (when added together 
) but the double-taps are ridiculous. Almost looks like somebody just did something temporary and forgot to come back and do it right.
Double tapped busses. A no-no.
3 AWG copper or 1 AWG aluminum would be the AWG required to feed a 100 amp service.
Is this a service or a sub-panel in a separate structure? Regardless, the minimum size parallel conductors permitted by the NEC is #1/0.

That’s improper wiring that has resulted in an overfused condition that is a potential fire hazard. Write hard on that one.

It’s a service
So for a 100 amp service #4 copper or #2 aluminum conductors would be the minimum size via the 83% rule. Also there should not be an EGC with the service conductors and the neutral is required to be bonded to the enclosure.
Are you sure that’s a service panel? With 10/3 coming in and the grounds and neutrals separated it really looks like a sub panel. Where do the feeders come from?
I thought that too but he said it is the service so I believe that he’s correct. It does have what appears to be bare copper GEC which would be run to the service not a sub-panel but then the green screw MBJ is missing. 
Was just out there again this morning, it is a sub panel.

Is it within the same structure as the service? Seems likes it wired for a separate structure.
It’s separate.
Well that explains why there is separate EGC and neutral buses, UF cable, and a GEC. What size OCPD was ahead of this feeder?
It’s hard to tell from my photo but I think it’s 100 Amp
The feeder OCPD would be on the other end of the feeder where it originates.
It’s fed from a main panel at the home next to it. Again I think it’s a 100 A breaker
