Leyline Witch unable to Merge

Leyline Witch doesn't seem to be able to merge with Angel with version 1.7.0 of Spellbook Merge and game version 2.1.0x. Mentioned by Loub#0125 on Discord, and I replicated it on my end as well.

I realize you are mostly away from Wrath's modding scene, but submitting the issue in the case that someone submits PRs.
