Unfortunately we detected this Language menu bug too late in the release cycle, and we released 2.1.4 with it. The root cause is that you did not have hunspell or myspell dictionaries installed. Try to install at least English:
apt-get install hunspell-en-us
In regards of the branding package, you are at the latest version, don’t worry. We don’t update it every time, it is quite stable. I’m sorry, if the version number number is confusing.
