Maybe its just the way Poco is configured: https://github.com/pothosware/pothos/blob/master/pothos-library/lib/System/Logger.cpp#L155

For example, the SoapySDR in the Message constructor get forwarded as the source, but when something is local, the logger path is set as the source: https://github.com/pothosware/pothos/blob/master/pothos-sdr/Logger.cpp#L17
