Sorry, I didn't see your message sooner (for some reason I didn't receive a mail alert from the forum).
If you notice leftover .wav files after SDSE has completed its task they are most likely extra Hats articulations that couldn't be used. Most SDX have less articulations than the maximum allowed in a .dsnd, but some have a little bit more. When exporting Hats SDSE makes some adjustments like reducing the amount of articulations, expanding them to even out bow/edge, preferring bow sounds to bell sounds when both are available. When there are too many articulations to fit a .dsnd it will use as much as possible and won't delete the unused .wav files (you can safely delete them if you don't need them). There are settings in SDSE.ini to fine tune all of this or if you'd like to export two versions of some Hats, one with bow/edge and another with bell/edge, or one version with tight sounds and another without.
Hopefully this is what you noticed, if not please send me a mail and I'll make sure to look into it.
