multi-WAN bonding cli quality metrics report zeros

[bde]

I am attempting to do balance-aware multi-WAN bonding to an AWS Server to provide link aggregation.
Note: not using a NAT gateway, as docs say don’t do that.

ZeroTeir documentation mentions monitoring links for quality metrics etc, and the below command shows said metrics however is all empty values.

I was thinking of creating a script to pull quality values out so I could monitor the link quality over time.

Is this an expected result as of the time of this CLI / Bonding version, or is something wrong?
Ive read through the git / blogs to see multi WAN bonding has had pending 2.0 changes, as well as the CLI had some changes coming soon.

I also don’t get why each link has 3 paths, would have expected one path per interface (2), or one path per the direction of traffic (4). ?? Does someone know if that’s normal?
