scom bug with the service level dashboard

I have a web application URL monitor here and I am attempting to remove a performance counter on which I have a service level objective set. Because of this, if I try to delete the counter from the web application monitor… I cannot and I receive this error.

Since I just made these service level objectives recently, I was able to quickly figure this one out, but the product really should handle this condition more gracefully.
