Hi there,
Thanks for writing in! Did you import Agency before the wedding demo? Would you mind providing the steps you took so we can try and recreate the issue and if it is a glitch or bug, try to fix it?
Upon checking your site, it seems that the slider did not change. You may be able to just switch sliders as it should have imported the wedding one into your sliders.
Let us know how that goes. Hope this helps – thanks!
