Not sure how this particulr Antipodes is constructed, but the device you are seeing may very well be considered the “transport”.
Hence, when enabling it, it will connect to your Aqua, and the correct line art will be shown (possibly).
Still, i am pretty sure support for these devices are handled by the manufacturer/retailers of Antipodes, not by Roon. Have you tried contacting your retailer?
Edit: It IS the transport, can be seen by it’s IP adress, which is an internal adress.
