Exclude one WAN port from load balancing

Hi,
I'm having ER605 v1 managed by Omada SDN Software Controller 5.6.3. In my setup I have 3 WAN networks as follows:
The first 2 WANs which are connected to WAN & WAN/LAN 1 port of the network are directly connected to the internet via two different ISPs. ISP 2 is having 100Mbps bandwidth and expected to be serving as the primary WAN. ISP 1 is having 50Mbps and expected to be serving as the backup WAN.
The 3rd WAN which is connected to WAN/LAN2 port of the ER605 is connected to a Cooperate Network though a firewall in the Cooperate's end. This firewall drops all the traffic other than specific for few network segments and then shows a captive portal.
Here is my configuration for this
I have configured a routing rule as follows to forward matching traffic to the Cooperate WAN
The issue I'm having is even I set load balancing weight to 1 (which is the minimum) for the WAN/LAN 2 and set significantly higher values to both WAN and WAN/LAN 1 ports, there are some traffic send via WAN/LAN 2 occasionally and users are seeing captive portal in their browsers. I believe this has happened because WAN/LAN 2 port is still considered for load balancing and 1/100100 of connections are going though the WAN/LAN 2.
Pease kindly to help me to figure out a way where I can completely isolate WAN/LAN 2 from unintended traffic.
Thank you
After evaluating options I have, I came up with a solution as below.
Since ER605 doesn't send any traffic to backup WAN port unless there is a failure in Primary WANs. So I have marked WAN/LAN2 as the backup while having both WAN & WAN/LAN1 as the primary.
With above configurations, even I have added my actual backup connection though ISP1 as a Primary WAN with low load balancing weight, ER605 is routing all the traffic via WAN, when WAN/LAN1 is failed. As long as ER605 activates WAN/LAN2 as the backup only when both WAN & WAN/LAN2 connections are down, it will no longer redirecting my users to captive portal while I have the internet connection from WAN or WAN/LAN1.
Hope this solution will helpful to anyone who is having the same situation as me.
