Camera has no metadata stream according to the Milestone Management, but it has in the ONVIF Device Manager

The camera in question is a Hikvision camera with a developer firmware, which has as a new feature to stream an ONVIF output. When I connect to that camera using the default ONVIF device manager software, I can read and get the software as streamed by the camera. But when I connect it to the Milestone Management, there is no option for metadata, now I wonder why this does not work?

I attached a wireshark log showing the handshake.
