Thanks for letting us know about the bug. I just checked in the change for the next release.
With version JFBConnect v4.2, we started using Transifex for our language translations and the bug was introduced there. If you'd be interested in seeing the translations before our releases come out and thus causing issues like this, feel free to create an account on transifex.com and request to be a translator for our JFBConnect project -
www.transifex.com/projects/p/jfbconnect/. We'd love to have your contributions.
Thanks!
Melissa
