My Menu Will Only Semi Translate
I think you will find there is a conflict somewhere that is preventing the specific word (as it is a link) from being translated, and this submodule should overcome the conflict. I would utilise the "Menu Translation" submodule as it will specifically achieve what you are attempting above, and hopefully make it simpler! I would use the Translate and Localize Menus option (a detailed guide of how to do that is here)

If you are still stuck, and are using SuperFish for your menus (even though this is supported in i18n), there is a work around here and this may overcome the problem also.

Lastly, just in case, ensure you have this update, the most recent version, installed also.
