I think that when you install a pack that includes expansion voices, the expansion voices use custom Bank MSB and LSB values. When you install multiple packs, I believe it's possible for these custom Bank MSB/LSB values to conflict with each other, and that the YEM program lets you edit those values as needed to make sure they don't conflict. It sounds like the expansion drum kits from the different packs might be using the same Bank MSB/LSB values as each other. I'm not familiar with using YEM, since I don't have any keyboards that can load expansion packs, but there should be an option that lets you see what Bank MSB/LSB values are assigned to each pack's expansion voices, and that lets you modify those values if need be.
