[Windows 10]Enchanted items no longer show signs of being enchanted

I had many weapons and armor pieces enchanted prior to update .16, but upon logging on, the items no longer produce enchanted effects though it shows the enchantment on the item.

Examples:
Bow running out of arrows despite having Infinity on it
Same with Flame (enemies not on fire)
Punch not punching enemies back
Pickaxes wearing down quickly despite having Unbreaking III on it

Using an anvil to add an enchanted book to a pickax had no effect on this issue. Combining two helmets dropped from skeletons had no effect. It is as if the enchantment is applying to the weapon/armor in name only, but not in effect.
