Firstly, I like your mod very much, thanks.
Because I'm not a native English speaker, I translated the mod content by myself.
I have recently found that some translated contents are invalid, that is, they are still displayed in English.
I'm sure there was no such problem before, but I can't remember exactly when it started.
I hope you can fix it, thank you.

What is no being translated ?

The whole GUI. Only [mod-name],[mod-setting-name],[entity-name],[item-name] are normal.

Tested here. It is being translated normally to PT-br, the extra languaged added to the mod. Please double check you settings and custom translation added
