SiteOrigin Slider is not displayed at Home Page.

Hi, I have checked out the vantage theme and it appears so professional that i am thinking to get premium version soon, even though i am a starter, but i wanted to thank you for that.

The problem i am facing right now with free theme is that:

SiteOrigin Slider is not displayed at the Home Page.

Additional information:
1. I installed Meta Slider Plugin.
2. I installed SiteOrigin Widget Plugin.
3. I access Appearances >> Home Page ( At the moment i haven’t created any separate Home Page).
4.I have selected the option a static front page from Appearances >> Customization. ( Because if i select Blog it display post and i don’t need any post)
5. Yes, I have upload Images in SiteOrigin Slider correctly, (both background and front images)
Important NOTE :
***6.Slider below Menu-bar is not the Issue, SiteOrigin Slider is placed under the facebook icon , in the left sidebar widget (where you can clearly see no slider is displayed).***

I have read the documentation also, right now i have no idea why it is not displaying. Please i would like someone to help, because its causing delay in my work, Thank you.

Regards
Rafay…
