Unit Sound Sets not working for some units and question about tree of life animation

[NecroVirus]

I'm trying to hang corpses from my tree of life boss but he keeps switching between his 3 upgrade forms in editor. I tried deleting anything regarding techtree/upgrades in the object editor but he's still doing it (but not in game). Is there something I can do to get him to sit still?

Also I can't seem to give neutral hostile based units new sound sets. If you switch the soundset of something like the felhound to the ghoul does it work for you? Pure silence on my end and not sure how to fix.
