Hello,
Perhaps this is intended, but I feel like reporting it, nevertheless.
With the mod active, that prevents zombies from reviving, corpses are no longer displayed in a different colour, to show the change that they’re no longer really dangerous.
However, Skeletons (and also Skeleton dogs, IIRC) are still displayed differently when a killed. So I assume, that they are also going to revive, unless butchered or smashed.
In my opinion the mod should just disable skeletons as well.
