Syslog Viewer shows incoming data, but data not being captured?

Hi, Running ME Eventlog Analyzer 11.3 (11031 / SP-11.3), we've had it monitoring a Sonicwall firewall for the past year, but it stopped collecting logs two weeks ago. 

In "devices", the firewall appears with "event count" "0" and "log collection status" "listening for logs", but nothing's being captured. There are 5 windows devices configured and they are working normally.

If I click on "Syslog viewer", I see a steady stream of data coming in from the firewall's IP address. The device is configured with the standard port 514, and the syslog stream shows the IP and port correctly. How can i get ME to begin capturing logs from this device again?
