SgtBundy, I've had a similar experience however I got a Class 1 with no such restrictions and they had a restriction of "for CASA audit" on the Class 2 with one year (ends up being 9 months as you say) expiry instead of two. When I queried it I was asked if I was flying commercially, "yes" was the answer .. so, the Class 2 doesn't matter. My reply was to the effect that one day I will get sick of dealing with them so may decide not to renew the Class 1 ... the clerk was quite helpful in general but wasn't her decision.
I should add that I have no complaint in my case. However the process should be swifter and more sensible in general.
Been a month since I paid for my last renewal so I guess mine is in a pigeonhole somewhere.
