The world sometimes does not load items from the addons' equipment tab, such as armor and equipment.

In the first video the addon works perfectly.

In the second video (in another world) the world does not load the equipment section.

PS:

1: I tested with several addons and they all show the same error.
2: It's not just an error in the inventory, it's as if the game simply didn't load that section
3: Both videos I used the same addon

4: ADDON used for videos: More Ores Addon Minecraft 1.20.41+ (attached below)
