Can't change Featured Post Slider order

First of all, thank you for this forums, there is so much information here that has helped me a lot! I am now ready to ask my question. I used to be able to change the order of the post slider, not anymore. http://rockflower.co.uk/ --- EDIT --- It is now working again! Maybe it takes a bit to update the new order? Thank you for your time and for these beautiful wordpress themes!
