blank slides error

I have installed that plugin, when I add 2 images as banner, there is one blank slide between 1st and 2nd slide……

Please review my banner at following url alburraq.com

When i added 3 slides, there are total 5 slides now instead of 3. One is real banner image and one blank slide.

Please help where is an issue!

Thanks in advance.
