Excessive logging: Table with same name already exists

I've been running a Firewalla Gold for a couple of years. I'm seeing this in my FireRouterX.log file every 20 seconds:

INFO Routing: Table with same name already exists: 9

I find this concerning as it goes on and on. The message is coming from the /home/pi/firerouter/util/routing.js file, but I don't know why. I am running Home Assistant in a docker container on my Firewalla. Can someone tell me why I'm seeing this repeated message and what I can do to stop it?
