Issue with lists in items NBTs

Summary

https://git.mythiccraft.io/mythiccraft/MythicMobs/-/wikis/Items/Items Following this documentation on how to create items with NBTs in mythicmob, lists of items are not working properly.

It happens in several versions, I tried Catserver 1.16.5 with the 5.2.0 and last version of paper 1.21 and dev build 5152

Steps to reproduce

Add an mythicmob item like this:

testItem:
  Id: stick
  Display: '&6Test'
  Lore:
  - '&6Test'
  NBT:
    list:
    - integer: int/427
    - value: string

/mm reload /mm items get testItem /data get entity @e[distance=..5,limit=1,type=item,sort=nearest]

You should get:

Current behavior

When performing /data get entity @e[distance=..5,limit=1,type=item,sort=nearest] We get tag: {list: [ ]}

Intended correct behavior

Instead of tag: {list: [{integer: 427, value: "string"}]}

Question

There are 2 possible explainations, either I wrote the syntax wrong and then the documentation could be improved with the correct syntax to use when coming to [ ] or there is an issue with lists management when coming to NBTs in items
