Multi-Server Monitor log outs repeatedly

I recently installed ColdFusion Enterprise 10 and set up 3 instances on the same server and then set up multi server monitoring for my three instances. The problem is logging into one CF admin on one port logs you out of the other. This appears to be affecting the multiserver monitor as well making it utterly useless. From the overview dashboard you can see the servers logging in and out repeatedly. Is this is a bug or is there something obvious here I'm missing?
