The right leg of the bottom capacitor could use some more solder.

Would that not being fully soldered cause my issue?

Yes, if the cap on the output of the regulator isn't well soldered, the regulator may not function properly.

Ok reflowed that one capacitor and triple checked the others, but no change.

At this point I’m not sure what I’m supposed to do.

I received your e-mail and replied with my mailing address.  If you haven't seen that, it's probably in your spam folder.

This issue turned out to be a meter issue.
