V9 flows of unknown template are received from...

I have enabled NetFlow V9 in an attempt to see if it fixes any of the issues with NAT being in the equation. However I now see the error message ' V9 flows of unknown template are received from..' displayed at the top of the main page. I can manually clear this but it obviously keeps returning.

The NetFlow parts of the Router configuration is:

interface Vlan10
ip flow ingress
!
interface Vlan100
ip flow ingress
!
interface Serial0/1
ip flow ingress
!
ip flow-export source Vlan10
ip flow-export version 9
ip flow-export interface-names
ip flow-export destination x.x.x.x 9876

I can't find too much documentation on here regarding NetFlow 9, am I doing something wrong or is there an issue with V9 flows in NetFlow Analyser 5 (version 5.5.0, build 5503).

Thanks

Andy
