It doesn't show a localised description for me, so I cannot reproduce this (on the dev branch).. That error could only show up if the base game is forcing it somehow? What version of factorio where you running at the time? I'm on 0.18.8 and it's not showing a description when hovering over it.. Does it still occur with the latest release of factorio?
I was on 0.18.6 but 0.18.8 was released that day.
