Ok thanks guys. I feel stupid now. I remember reading this a while back and it must have just fell out of my brain.
I assume it is because these APs are on upgraded OS version that changes way they function now as I was used to just getting a new AP out the box to install and using admin admin.
Still have the issue with being unable to reset some of the APs. This seems to have been caused by a controller cluster upgrade so not entirely sure where the post belongs but regardless of the controllers I am still unable to reset the unit back to factory as it stays as a campus AP instead of reverting back to IAP. I have been able to connect to console output of the AP and it looks to work ok and just boots up then reboots over and over but no matter what I try it won't revert back to an IAP.
Cheers.
