Hi shashad,
Your question has been answered here:

Also, just created more in-depth documentation for the slider here:
https://startupwp.com/topic/setting-up-the-slider/
We’re dedicated to support and making our customers happy. But, it’s important to note we only just officially launched a few days ago. The products and documentation are going to get better and better as we evolve and mature.
If you would still like to proceed with a refund and to discontinue using StartupPro and receiving upgrades and support, we’ll take care of that for you right away as guaranteed.
Thank You
