Pro Plugin Added but Alternative Homepage feature not available to customize

I have upgraded this theme to Pro and it states that I should be able to now have an “Alternative Home Page” available in the customize section; however, I don’t. I followed the steps perfectly. Other features immediately became available but not this. I also went through every suggested step I found on google with deactivating all plug ins and reactivating one by one, trying it on another desk top computer, making sure my server allows enough space, etc. I am simply trying to achieve virtually the same look of Kenza’s pro version with the home page but the “alternative home page” option is not under “front page” section of the customizer as the instructions say. Its also not under any section for me to customize. I sent a ticket to the developer and not receiving any response.

Please help, what can be done?
