I had the same problem and discovered that no media will be removed if the clip does not have a reel number. I had to go in and manually insert an arbitrary “001” in the reel column of each clip I wanted to pare down.

That doesn’t mean that I didn’t have to go back in and cleanup the mess created by Media Mangler. The new clips ended up in a temporary folder, not in the original folder, so I had to move them to the original folder. I also had to go through each clip and make sure it was named and linked properly. But a couple of hours later at least I’d pared down that project folder by several gigs.
