The Spanish labels.inc that I previously submitted were approved in SVN 408 includes some fields that do not belong the the RoundCube trunk, and should be removed. Those fields are translations for a extended contact information.
Info about the bug can be found here: http://trac.roundcube.net/trac.cgi/ticket/1484172
Included are both the new revised es/labels.inc without those fields, and the diff that removes it from the SVN trunk repo (v414 at the time of this writing).
Sorry for the inconvenience.
Mario
