Reply To: Admin bar translation?
Here what i have on my test install, 2012 + wp+bp in spanish

as you see, the wp part IS in spanish, and most of the bp items are in english, and some are in spanish.
Guess you have to review the whole translation manually with poedit or at least try to setup your site to another spanish format, so that bp could use that one. With a little chance, one of them is correctly translated.
Open the po file with poedit and update it with the POT file shipped with BP 2.2.1.
And complete/modify the translation, save and add the mo file to live site languages/plugins/ directory.
