You need to remove the references of that variable as well. In later release 3.6.2 version, we're going to optimize this behavior.

Sorry，this optimization too late to catch up v3.6.2 , would be delay to v3.7 . On v3.7 when remove a variable ,if the variable is be used would pop a confirm warning dialog to user.
