Global Change - How to Filter Out Milestones?

I'm trying to reduce durations on activities that have a duration between 8 and 35 by 1 day. These activities are reduced as expected, but I keep getting an error and the change keeps showing three milestones that, of course, have zero days duration. I tried filtering for only task dependent activities, but the milestones show up. I tried filtering out milestones, but the milestones show up. In the screen shot below, I tried to filter out activities with zero days original and remaining durations, but the milestones show up. I know the Global Change will work with this error,
