Slider affecting the wrong part of the mesh

I created these jeans from existing EA jeans, and the bow was added from a base game dress. I removed the weights from the bow and added the weights to the calf vertex. It moves well in game, everything seems correct. However, the slider still grabs the bow as if it's part of the waist area {where the bow was on its original mesh}. How can I fix that?
