VPN - traceroute showing ISP ip address

[Free_Norway]

Hi all

I use opnsense in a multi-VPN-WAN loadbalancing/failover setup.
The setup is from my vpn provider forum for setting up a multi wan vpn firewall, all traffic routed through one of the vpn wan's.
Today i tried traceroute and the result is showing my ISP ip address.
I tested my setup with 3-4 DNS leak test sites and all are reporting no DNS leaks.
Since i'am not a firewall expert, my question is:
Is this an expected result?

Thanks in advance :-)
