High amount of errors after installing and disabling MQTT Transmission module in trial mode

We've installed the MQTT Transmission module on our gateway, and it is generating log errors constantly. I've disabled everything I can in the module configuration but no luck, including the example transmitter and deleting the default MQTT broker configuration.

Does anyone know offhand how I can get these errors to stop flowing? I understand this could be a better question for the Cirrus Link forums.
