Using Simply Tools 1.19.1-1.1.3 - without More Vanilla Tools (haven't tried with it) - the enchantment names and descriptions aren't showing up ingame. This can easily be fixed by editing the localization files in the \assets\simplytools\lang folder:

enchantment.morevanillalib.power_of_the_depth should be enchantment.simplytools.power_of_the_depth
enchantment.morevanillalib.power_of_the_depth.desc should be enchantment.simplytools.power_of_the_depth.desc
