VenusOS 3.90beta9: DC-DC node (testing Emergency Charging feature)

Running 3.90beta9: Testing Emergency Charging feature.

I have two Orion XS-50
Trying to setup a DCDC node in Node-Red,

The following boxes are greyed out, I can’t use it.

Using: @victronenergy/node-red-contrib-victron, 1.7.29

Just a reminder to please follow the beta topics how to post guidelines and not to add issues to the change log.
Nodered and signalk are large image features and are best posted in nodered and modifications respectively, using their beta-nodered or beta-signalk tags.
I will relocate this accordingly.
Thanks.
