Thumbnails break grid

Hello,

I use tiles grid gallery in one web.
It always works correctly but now it show me each image with one size.

You can see it in this page: http://www.juanmarcoarquitectos.net/portfolio/casa-en-un-bosque/

I have reviewed all settings and all are correct, all images have the same parameters and sizes. But in front-end this don’t show right.

I need help because with CSS or JS is very difficult fix the problem, and that all work right in the future with new updates, etc.

How I make??
I hope reply, thanks for your time.
