Describe the bug
In the process of adding new ench. update crafting, I found that enchantment improvements only work for the last item in the list of levels, thus, it is possible to make enchantments of only the last level, REI also shows the recipe of only the last level.

It works the same way for vanilla enchantments and new spectrum enchantments.

Minecraft version
1.19.2. fabric

Mod version
spectrum-1.7.6-deeper-down

Screenshots
This example shows the recipe for only the last enchantment level, but two levels have been added, according to the documentation!

Could you try it out without mods that override the default recipe viewer, or support adding/removing recipes via scripting languages, like KubeJS

I'm sorry, I'm an idiot.

Somehow we had 2 versions of kubejs in our modpack, deleting the second one made everything work.

Without kubejs, everything works as it should.

Do I need to write to the kubejs authors?

If the problem is with kubejs, why is the problem only with crafting this type? I have not encountered the problem of custom recipes yet.
All crafting of this type breaks down in the same way, it's strange.

In that case it very much sounds like KubeJS-Mods/KubeJS#293

Huh, I did not even know that was possible. Interesting. Glad it worked out!

In fact, the problem appears after a /reload
As soon as you rejoin into the world, crafts reappear

We noticed the same problem in the NeepMeat mod - MeatWheeze/NeepMeat#5
The author rewrote his crafts to vanilla recipe manager
