[Plugin: NextGEN Gallery] Bug? – thumbnails not showing right

Hello
IMAGE

As you can see on the image there is a bug with the thumbnails, I had this plugin on 3.3.1 and it worked fine, now that I am on 3.4.1 not well

I have removed all the plugins and running Twenty Eleven 1.4 theme, still the same.

Is this a bug or am I doing something wrong?
