Items are not fluid

[Vojjtosos]

Hey guys, just came across your carousel and it is nice.

I have just one problem with it. How you can see in the picture on the right, there is a small part of next image. This is my setup:
$(document).ready(function() {
$('.owl-carousel').owlCarousel({
loop: true,
autoplay: false,
nav: true,
dots: false,
center:false,
autoWidth: false,
navText : ['',''],
responsiveClass:false,
responsive:{
0:{
items:1,
},
600:{
items:3,
},
1000:{
items:6,
}
}
});
})

I found out, that if i resize the window and then came back there is already 6 items (without the small part on the left). Is there anything iam doing wrong?

Thanks for answer!
