Activating delegated harvesting on a primary account with importance

Is there any reason that when someone clicks delegated harvesting in their primary account in the XEM wallet nothing happens. However, when clicking delegated harvesting on another account in the same wallet which isn’t a primary account and has no XEM in, delegating harvesting opens up the popup with the 6 hours message.

Basically, what I’m trying to do is set up delegated harvesting, previously being a local harvester. Do I use my primary acct, which has an importance. Or should I make my account with XEM and importance into a non-primary account, and then activate delegated harvesting?

Actually ignore this. I’ve just restarted NCC service to get this working.

Thanks for the update always good to report a “fix” for others
