Enabling DRC with component rules

Never had to use it before: Component Rules. I want to route (and pass DRC) using 3/3 trace/spacing within a BGA area but allow 5/5 rules outside of the component area. I selected component, show rules and assign appropriate values in the DRC matrix but Verify Design (Clearance) continues to flag errors 'distance is less than 5'. All nets connecting to BGA have a general setting of 5/5 but the DRC is not observing the component rules settings. Are there additional settings or processes required to make Component Rules work?
