Letting us know what's actually happening would be helpful :P You've described your setup fairly well, but we don't know how it's behaving or how that differs from what you expect.
Also the 'WAN1 net' rule should not have a gateway, the system routing tables will take care of this automatically because pfSense is directly connected to this network, as long as the traffic is allowed by the rule you don't need to specify the gateway. You generally shouldn't have gateways in your rules unless you want to modify the default behaviour or use load balancing/failover. Just the default rule with the failover gateway should suffice for what you're trying to accomplish I think. Your rule for destination 192.168.0.0/24 also doesn't make any sense - isn't this your LAN subnet?
I echo all of dotdash's comments. Since you've masked your internal NAT'd WAN IPs (why would you do this, they're internal…), I can't tell - but if both of these use the same subnet, dual WAN is not going to work. You'll also have issues if either of them use the same subnet as any of your LANs. Either move them to different subnets or preferably get a real IP for each WAN link on pf. I suspect this is your problem based on my guesswork about your addressing by the way you've named the rules.
Your configuration looks generally correct to me though aside from these comments (as in it should be working as long as the subnets are different), so I expect the 'problem' may just be that your expectations differ from how you've configured it.
