Sword Enchantments aren't working properly

Description: 

Sword Enchantments that deal damage aren't working properly

Smite doesn't increase the damage done to undead mobs as much as it used to 

Sharpness is dealing VERY little extra damage

 

Ways to reproduce:

1) Grab an unenchanted sword, a sword enchanted with Sharpness V and an sword enchanted with Smite V (Diamond or Netherite)

2) Place a mob down (preferably a Zombie, but make sure it doesn't take any damage due to sunlight/enviroment)

3) Kill it and repeat the process with different swords

Note: A regular unenchanted Diamond sword takes 3 standard hits to kill a Zombie, a sharpness V Diamond Sword takes 2 standard hits to kill a Zombie 

(Standard = Fully "charged", no critical/sweeping/knockback attacks)

 

Expected Results:

1) Zombie dies in 1 (critical) shot with the Smite V sword

2) The sword encahnted with Shapness generally deals more damage

3) The "Attack Damage" Tooltip in the Shapness Sword changes

 

Observed Results:

1) The Zombie doesn't die in 1 critical hit with the Smite V Diamond Sword

2) Shapness V Diamond sword doesn't deal that much damage (See Note above)

3) The "Attack Damage" Tooltip doesn't change
