I found two problems so I report them.

1. Since I installed this mod, NEI mod don't display left half of their GUI on the inventory(1).

2. When I use Japanese language, Item name is not displayed correctly.
   When I use UK English language, Items' names are displayed correctly(2).
   But When I use Japanese language, they are displayed as non-readable words(3).

Thank you for reading this issue.

Some strange issues and not marking this as closed yet. Basically what I have done is updated the resource folder by correctly added an mcmeta file. From my testing, Japanese is working correctly for me. I would look into NEI potentially ruining rendering after I release this update with a potential fix.

I've also changed the buttons in the creative GUI to be added on Post, hopefully fixing the issue but I'll get back to you on that as I cant run NEI in a deobfuscated environment.
