Mesh doesn't work with sliders properly

So, just as the title says, my mesh doesn't work with sliders properly. As, you can see in the pictures below, on any other body type that isn't the default one I used when making the mesh, edges are jagged and it doesn't look good. If it matters, my sim settings are set to very high and smooth edges(or whatever it's called) is set to high so I really don't know what the problem is.

This is how it looks on the body type I used to create the mesh.
