Transalations not Fully working

Hi, i downloaded and imported the translation file for this plugin (Spanish translation, which is 100% translated) but there are certain things that are still in english.
here an example: http://www.comunidadcrm.com/eventos-presenciales/2015/09/15-de-octubre-enterate-lo-que-se-vendra-en-microsoft-dynamics-crm-2016-mesa-de-expertos-mvps/
As you can see "About this event:" is still in english, and in the Spanish PO file (named eab-es_ES.po) is correctly translated.
Just in case, i granted support access
