[Plugin: Google Calendar Events] I can't remove the bullet style from the title

Hello, I want to remove the disc type of the gce-list-title, but even if I add it by doing this:

.gce-widget-list .gce-list .gce-list-title ul{
list-style-type:none;
margin:0;
padding:0;

}

my theme overrides it and it shows the disc 🙁 you can check it on http://www.iglesiazambrano.com/noticias/

What am I doing wrong?

Thx in advance!
