Lich drops enchants from the dungeons and taverns mod and im pretty sure this is the case for other datapacks/mods that add custom enchants.
Kind of a bummer since those enchants are supposed to be drops from defeating the dungeons so was wondering if there could be a fix for this.

Minecraft version is 1.21.1 and BOMB version is the latest at the moment(1.10.2).

I'll just add why it does this, basically the enchant function needs an options field in 1.21+
Else it'll just pull from everywhere, including vanilla structure enchants like swift sneak and soul speed.
