So I've been trying to add ancient tomes to certain loot tables both in vanilla and the repurposed structures mod loot table, but whenever I added anything my Minecraft has significant issues trying to read the config file

How do I add the tomes to loot tables/new enchantments? I tried adding them ingame but the config menu refused to let me type anything when I try and add enchants/loot tables.

Update: So when I go out of game I can add tables but its very fragile for whatever reason, like sometimes it won't let me type and other times it'll just crash
