Can't edit Risk Description when inherit from Risk Statement

We just installed IRM. If I create a risk from a Risk Statement, the Risk inherits the description from the Risk Statement, but it doesn't let me edit that description for the risk. Is this the way it suppose to work? I would imagine that it should import the Risk Description from the Risk Statement, but it should let you edit it if necessary. Can anybody clarify for me why this happens?

Thanks for your help.
