Nice Plugin, terrible support, translation doesn't work

The plugin looks nice and works well enough. apart from the nutritional fact which is a disaster and there’s no way to personalize that.

I run my blog in three languages for which CodeStyling Localization. I expected the plugin to be automatically translated because that’s what I found in the few responses I found.
I contacted the support for this problem and while I had explained everything and they said (after a long time) I need to use localization! So I replied I am already using it as I had stated. I asked for some detailed info to maybe guide through, in case I wasn’t doing something necessary. The (late) answer was again to use localization with the correct language files! Which I know that I already am, since everything else, other plugins included, are well translated.
No more answers received and weeks have past.
