Looking at your configuration, for the mouth parts to successfully swap, they need to be at the same level - both need to be subsets of the same mouth layer and you then make a swap set out of that mouth layer. It looks like you have the happy mouth on its own as a subset of some other layer or part. Hard to tell from this image.
