You can change the number of significant digits by scrolling down further and entering the number of digits accuracy you want. Don't press the enter key. It resets the calculator. Just enter the number of digits accuracy you want and then scroll back up and continue without pressing the enter key. If you entered your angle and it's still in the input box, then press csc. Otherwiee re-enter the angle and press csc. That's the only bug with this calculator. Otherwise it works fine.
