Pc2 and remapping

Hello everyone. I am in desperate need of help. I simulated an animated dress object in MD, imported the obj to blender and added a mesh cache modifier referencing the pc2 file. I then tried to remap the time in Blender and the viewport shows everything working well. But when i go to render the scene, the avatar begins to show through the cloth. It’s as if the two motions are not in sync. Can someone please help me? This is for a school project and I’m beginning to panic. Thanks!
