RKB 6.0 New Vocals feature not available on an approved Unlock-Device (DDJ-800)

I upgraded to Rekordbox 6.0 manually as the auto-updater did not seem to work.

Sadly it appears that im not able to use the new Vocal analysis feature on my DDJ-800. It says I need to upgrade my plan.

However my Controller is an Unlock-Device. Is this a bug?
