**Attach debug file `sudo generate_dump`:**

Not log file. I think the issue here is that "show interfaces neighbor expected" is not showing all interfaces. From looking at the diff. I think for all dual member lags, only one lag member showed up in the output. E.g. Ethernet0 and Ethernet4. Only Ethernet4 showed up.
