you are not on the CAA register
It's normal for only one or two Group members to show as CAA Registered Owners. We've got one at present - we've never had all six appearing on the site. If you own a Group Share, then you're OK. I'm not sure if the CAA even need to have you on record.
(I was one of the two Registered Owners when a third member had a fatal accident - there was no problem with insurance /AAIB / CAA.)
