I've taken a quick look at mwan3 and it seems to mark every packet with a fwmark. This probably conflicts with NetBird, that also makes use of fwmarks to prevent routing loops.
Setting the env var NB_USE_LEGACY_ROUTING=true should circumvent that. It does the same as NB_SKIP_SOCKET_MARK=true which you seem to have found out already

Just to let everyone know - I have had compatibility issues with Netbird and Policy Based Routing package in OpenWRT. The PBR also seems to use fwmarks. The PBR was configured to route some IP range through VPN connection (other than netbird) and to my surprise the netbird connection was routed as well even though it had nothing to do with that routed IPs. This was evidenced by showing public IP of routed location in peers tab of netbird GUI.

After setting the NB_USE_LEGACY_ROUTING=true it seems to be fixed and correct (not routed) public IP is shown in peers tab.
