Boostrap is collapsing on Evolve

Hi, please check my website, http://www.e4arts.com.br and you can see that the slide with MJ is malfunctioning. It sorts of collapses and it s not fully opened as the others. Please help. PS. I need really detailed info as I am total clueless when it comes to proper terminology.

Your help is very much appreciated .

I also am unable to remove the RSS bottom from the Header menu.

Regards
Everaldo
