Hey there.
I'll see about updating those text strings soon.
As for the red box, that box is there for selecting a wildcard ingredient. If the recipe contains one, when you select to craft it, the craft button forces the user to pick an ingredient that matches the category of the wildcard ingredient, using that window. I could put in a plugin parameter to hide this window and extend the result item window to compensate, but then if it was hidden, recipes with wildcard ingredients wouldn't work right.
