Can't get mobs to drop custom loot tables but the chests are able to display the loot table

Title is states my current problem. I don't know where I went wrong I followed 1:1 the tutorials on custom loot tables and I can't seem to get it to translate to mobs. I know the loot tables are working as intended though since i'm able to access it using the container_loot command.
I'm using version **1.21.6 ** and the original name of the folder was loot_table, I forgot to revert it back when taking the screenshot
