Plastic GE remote/sub panel

I’m looking for some advice on this sub panel.
So far I have noted in the report: Surface wiring, the feed for this panel is double tapped in the main panel, grounds and neutrals should be separated.
Is this correct?
What else is note worthy?
This sub panel feed a time of use device (from the utility) for the a/c unit.






The sub panel installation is an “unprofessional” installation at best. The feeders to the sub panel are just wrong - don’t worry about the fact they’re double tapped, just call for replacement.

Thank you Jeffrey.

I agree, paralleling of the two NM cables is the sign of a complete amateur and can be dangerous.
