In moving tasks problem of same "task list" name in different "mile stones"

In moving tasks problem of same "task list" name in different "mile stones"

I have the same "task list" name in different "mile stones".  While moving a task only "task list name" is listed in the combo for destination, however, since I have the same name in different mile stones and mile stone name is not displayed, I can not find the right "task list" to move :(

Could you please add/append mile stone names in the task lists combo box.
