Passing Council Tax Band to Right Move

We have a problem trying to pass a value for Council Tax Band from Property Hive to Right Move.

The value is showing on the website but is not showing on Right Move

Right Move support replied with this message:

To confirm within the plugin are you able to add new fields, to be sent in the feed?
