Controling hAPac2 wifi with capsman

I am just in the process of configuring up CAPSMAN on my hAPac2.

I am trying to control the Wifi on this unit by capsman on this unit.
I have gone into the cap button under wireless and set the information as per the screen grab

When I click on ok the interfaces are showing as managed by capsman but within capsman nothing shows up, no interfaces or radios etc.

Can anybody give me some pointers as to where I am going wrong?

Many thanks,

Peter
