delete communication channel from comm channel monitoring

Hi

i want to delete the communication channel from the communication channel monitoring.

i deleted all the designed and configured for that particular scenario.

when i see the channels in RWB....>component monitoring.......>adapter monitoring.....>communication channel monitoring.

here i m seeing all the channels, i deleted all the channels in ID but i am seeing the channels here.

i want to delete those channels, i didnt find ant options there to delete the channels.

can any one tell me how to delete the channels from the communication channel monitoring.

Thanks
