Troubleshooting > Logs > Firewall Logs missing

Yesterday I noted the firewall logs were missing from my router.

Troubleshooting > Logs > Firewall Logs missing. How could they disappear. I called Comcast Business Support and they noted there was an update rolled out two days ago. The system logs are missing prior to yesterday as well. The system logs stop at Nov 30th.

Anyone have any ideas?
