I'm not exactly sure what you mean about the cluster display. I use HRD v5.0 build 2893. The cluster has only displayed on the logbook page for as long as I've used HRD, which has been only the beta 5.0 version. As far as band changes, I can click on any spot within the bandspread display in logbook on the right that shows the entire band and the rig will change to that frequency, no matter what band I happen to currently be listening on. Are you having any problem with the computer control of your rig otherwise? Does HRD appear to fully control the rig without any problem??
