I changed the structure of the file as LineDev told me.

The Japanese category name was rolled back and was in English.

I forgot to change the namespace!

I didn't even need various_configs!

Removed ia_gui.yml and moved the category to the variable_configs folder.
I feel like I've fixed some weapons that I forgot to add to the category.
(It was so long ago that I forgot!)

Unzip the zip so you can copy it immediately
Adjusted the file.

Sorry ia_gui Forgot to insert
