syslog - [a locally administered MAC address] not mesh client, can't delete it

[ggbal]

My configuration is
RT-AC86U Merlin 386.5
Mesh RP-AC55 3.0.0.4.384_83577-gedb41ae

I observed there are always a few locally administrated MAC addresses that appeared in the mesh node. I can't figure out where they come from. I disabled all the devices connected to mesh, reboot both router and mesh node. Yet, the mesh node still shows there is one client with the locally administrated MAC address connected. My ethernet backhaul mode is enabled.

I checked the syslog, and I see the following
kernel: 62:6C:FB:B61:19 not mesh client, can't delete it

Anyone can point me on how I can pinpoint where this address comes from?

Thanks -
