Weird URLS

Hi I have a problem with my website, every article I create in K2 it results with duplicate urls.

For example:

www.eventosbarcelona.com/performances/light-graffiti-eventos
www.eventosbarcelona.com/performances/li...os?jjj=1488412840002

www.eventosbarcelona.com/en/venues/arena...e-event-organisation
www.eventosbarcelona.com/en/venues/arena...on?jjj=1488240040002

This happens in hundreds of urls and i don't know why its happening, and its affecting my website with lot of duplicate content, anyone can help me?

Thanks in advance,

Mauri
