Minecraft 1.16.3 Custom Villager Trades with Custom Items Issue

Question

I'm creating a custom villager Trading with Custom Items. It is way more complicated, but this is the essence of my question. Thing is, when I use the code I made below my Villager trades look like this: When the paper should look like this: aka. enchanted and Named, and the Chicken should have a custom Name as well as a Lore. The second Trade is completely messed up, as nothing is showing at all, when there should be a trade "4 Drachma" for "1 Miles' Delicious Rabbit Stew".

Problems

1. Lines 17–20: When you enter JSON, the entire raw JSON text is a string tag, not NBT formatted like JSON. For example, the following is incorrect:
   
   and the following is correct:
   
2. Lines 22–27: Enchantments is in the wrong place. It should be outside display but still inside tag.
3. Lines 28–31: Same problem as #1. Each item within the Lore tag should be a string tag containing raw JSON text, not compounds simulating JSON.
4. Lines 44–47: Here, you forgot that names have become JSON text components. Just like line 6, you can use \" or you can use a full JSON component like in the images above.
5. Lines 59–64: Same problem as #1.
6. Lines 65–71: Same problem as #3.
7. Lines 72–77: Same problem as #2.
8. Lines 85–90: Same problem as #4.

Just fix those 8 and you'll be good to go!
