In Lightroom CC when you click on the cloud (where you see the sync status), under the disk space status bar it's says "XXX,Y GB gratis" and it has to say "XXX,Y GB libres".
"Gratis" in spanish means "free of charge" (refers to money) and not "free space".
It's a really bad translation and it rest seriousness to a top level software like Lightroom.
