Slider Revolution – responsive version

Hi,
I used a template as a starting point – and nearly have it just how I want it. However, I have a problem with the mobile version of the site. I created a new slide on the homepage which works fine. But when i test it on the mobile version – it is replaced with another slide depicting a chair (simple rock chair) – How is this swapped out. Where can i find settings to control this replacement?
Many thanks!
