Why does changing the name of a subchart in Stateflow 8.0 (R2012b) delete the other text in the subchart?

For a state with a subchart option activated, if I select the state name (which is the only thing visible at the level where it is contained) and then double-click in the main area below the state name (which is the way to open the subchart with the mouse), all the text in the subchart for that state is lost except for the state name itself, which I guess is happening because the state name is pasted over the (state name+state actions and text) in the subchart.
