I don't know the settings off the top my head, but if you want a setting that would prevent you from having issues with the bell not triggering right, you could change the zone type to one where the bell sound is on the edge zone. Now if your have your ride/bell cymbal and have relatively long arms, you can hit the far back side edge of the cymbal, and trigger the bell that way. This removes the bell sound in the center of the cymbal and puts it on the edge. Of course this would have some negatives with playing the bow, and bell in the traditional way, but it's more accurate.
