Dual WAN, ping request goes in the correct interface and out the other

[Tubal]

I've gotten service from a 2nd ISP, and I'm trying to set up a 2nd WAN interface.

If I ping the IP for the 2nd interface, the ping request gets to the pfSense box, but gets routed out the original default interface/gateway.  So I never get a ping response.

What I would like to happen is if pfSense receives traffic on WAN2, it responds on WAN2 rather than WAN1.

I've set this up on other boxes without issue, but for some reason I can't seem to find the problem on this one.

I've attached my gateway list and the firewall rules on the two WAN interfaces.

I don't know about your problem specifically, but you really need to get rid of that Allow All (aka Default WAN pass rules) rule on WAN.  Firewall rules are processed on what is coming INTO an interface, not what is going out.
