Bootstrap carousel transition glitch

[trtksa]

I have a problem with bootstrap carousel. I added custom controls and I styled them according to design, but when I am clicking next slide the previous image disappears leaving white space in the middle. I edited the bootstrap.css where I changed the .carousel-caption and I added some custom css for the buttons. Here are the test page: http://valters.me/b/And I managed to take a screenshot: http://d.pr/i/yGzY
