Bxslider bestsellers not display all

[Serial]

Hi,

On my homepage, the slider of best sellers display just 4 slides... Why ?

 

This is my bxslider param :

$(document).ready(function() {
	if (!!$.prototype.bxSlider)
		$('.bxslider-bestsellers').bxSlider({
			minSlides: 1,
			maxSlides: 15,
			slideWidth: 270,
			slideMargin: 22,
			pager: false,
			controls: true,
			nextText: 'Next',
			prevText: 'Prev',
			moveSlides:2,
			infiniteLoop:true,
			hideControlOnEnd: false,
			auto: true
		});
});

 

Any ideas ?
