SignalK does not see Yacht Devices NMEA 0183 Gateway YDNG-03 as source

[Sailor-55]

I pass NMEA 0183 GPS-data via a Yacht Devices NMEA 0183 Gateway YDNG-03 into the NMEA 2000 network of my boat. This Gateway is comparable to an Actisense NWG 1 Gateway which works well in the system. The Yacht Devices Data are correctly available in the NMEA 2000 system and I can see Position, Speed data etc. on my Garmin GMI 20 device. The NMEA 2000 system is connected to a MacArthur HAT but unfortunately especially the GPS data are not available in SignalK. SignalK does not see the Yacht Devices Gateway as source and consequently no GPS data. All other devices like Garmin GMI 20, Actisense NWG 1 and Airmar Transducer are correctly listed as source in SignalK and data are available in OpenCPN.
I would appreciate if anybody could give me advice to solve this issue.

I can't think of any obvious reason this would not work. Do you have any Source Priorities setup?

If you get a log of the data, I can take a look.

I am currently not on the boat, thus I can not take the requested log of the data today. I will come back beginning next week.
