I'm struggling with sending navigation data from Expedition to H5000 / NMEA2000. Curious if anyone could tell me what is wrong in my setup. I've read few topics on this forum and some of them have similar unanswered questions.

My setup: Expedition, H5000 (2.0.45.0.34), Zeus3 chartplotter. All are on NMEA2000 network and H5000 is connected to PC with Expedition via ethernet and websockets. Activesense is only used to get AIS data to Expedition, all other data comes from websocket. Expedition is able to communicate back to H5000 - starting line and starting gun set in Expedition is successfully reflected in H5000 and displayed on B&G displays in cockpit.

I would like Expedition to send the information about the next waypoint to B&G, so that distance to the mark and mark bearing values could be used on displays. the "send navigation data" to websocket is on,  chartplotter is off, navigation source is set to CPU. nothing is happening in B&G once I set an active mark in Expedition, as if H5000 doesn't know anything about the mark, values show just dashes.
I can export these values as user values and display them as such, but the checkbox suggests that there is a way of exporting them as navigation data. 
Any ideas what could be wrong?

I also tried to export waypoint information via activesense by turning on respective PGNs - no success. nothing appears on the screens, I never saw Expedition / PC as a possible source for navigation in H5000 in the dropdown.
