Unable to connect signals vias harness

[kratikus]

Hello,

I've been struggling to get some signals from a multi channel design to connect using harness.
In principle there are 37 signals which have to be connect to diode arrays, but Altium somehow does not create the connection in the layout.
Below you can find a picture of the connections.
Another thing bothering me, is that Altium shows that the signals coming from the diode array are not connected to anything and that the net labels for the signals coming from the LED are out of range.
Can anyone shed some light?

Thanks
