Masonry Portfolio and flexslider combination

Hello,

I'm trying to combine those two things, but when I add the flexsliders, the third column of the grid jump to the left (leaving a blank space to the right side) and a big space appears (a margin) at the end of the page.

These are the examples (to see them you must load before the url http://www.stbestudio.es/?ign_skip=verlaweb , because the site is not yet public):

This is the portfolio page, without flexsliders: http://www.stbestudio.es/portfolio/

And this is the same grid, with flexsliders: http://www.stbestudio.es/eventos/ ['Presentaciones', the 6/7th grid has a slider of two images]

Could you help me out? I'll appreciate it :)

Thanks in advance

Hi again,

Problem resolved. It was that all articles had the flexslider classes, even those have just one image. Now everything works and looks fine.

Sorry for the inconvenience and thanks for your time.
