...

should I make the same correction in the other language templates?

If it's supposedly the same style template (eg "default"), can it hurt anything to make the same fix?

I would think not, but I noticed, for instance, that the German translation of the default template was significantly altered from the English version, leading me to wonder if translators felt some particular 'ownership' of them. I guess if anyone is bugged by my corrections they can always change it back! -- Owen
