How do we change the name of a film festival?

The Málaga International Week of Fantastic Cinema (https://www.imdb.com/es-es/event/ev0000842/2013/1/) has changed its official name years ago to ‘Fancine – Fantastic Film Festival of University of Málaga’ (or ‘Fancine – Fantastic Film Festival of Málaga’, both names are correct).

Just in case, its name in Spanish is: ‘Fancine – Festival de Cine Fantástico de la Universidad de Málaga’ or ‘Fancine  – Festival de Cine Fantástico de Málaga’.

This is the website https://fancine.org.

I am not able to change it in the events page. Could you change it for me or help me to do it?

Thank You.
