I had the same problem using IE 11.0.9600.16521 (Update version 11.0.4) and 10.2.1 GEP.
I'd drag and drop or double-click Filter and nothing would happen. Do the same on Processor and the configuration window popped right up.
I was able to get the Filter to work by switching over to Firefox 25.0, so I'd say give that a try.
