It's easiest to show you by example. In the Dictionary of the Old Testament: Pentateuch, there's a reference to 1QH 3:32–36. If you hover over this reference, it rightly translates it to 1QHa Col. xi:32. However, clicking on that link goes not bring up the DSS as it should do. Indeed, if you enter that reference in the DSS it won't take you to the right place, either.
