Okay, as near as I can determine, here's what happened with those.
The original version of necrotic healing was originally unlimited; it could basically be used at will. We realized that was way too good; cantrips that deal necrotic damage exist, and even inflict wounds is unbalanced for use as a healing spell, even with a limited target list. We realized between Light & Dark and Complete that it was still too good as a short rest feature, so we nerfed it some more.
The typo in the spell list was entirely unrelated; I had to manually reconstruct those because formatting doesn't transfer from Google Drive to Affinity, so that was almost certainly just a copy-paste error because I was using a different table as a template.
