Operational Status Unknown on Cisco WiSM

Question

Hello,
I have a pair of WiSM 2's managing our wireless AP's but i have a couple of access points that show their operational status as unknown on one controller but are happily working away on the other at the same time. Some settings are missing eg IOS ver and Regulatory Domains when viewing the info on this controller for that particular AP almost as if it failed during its initial setup?.
How can i remove it from the database on this controller?
Thanks,
Mat

A bit of further info, i've tried to force the ap to associate with the controller where its already in an unknown state and seen this
