Does anyone know why I get several spaces on top and below of both "

 
Publicado en..." and "Comentarios" and "Leer Más" in each of my category items?? My web is www.fakyea.com/joomla
 
Also, how can I put a "Back to..." in each K2 item?Thank you very much!!!

Thanks for your help! Your advice combined with some issues I resolved has made the web look right now :)

Thanks again!
