After Book Load Cover, the whole section disappears

Here is the video.

I am using a template which I bought, and I guess I did something wrong.
Book Load Trigger is in effect. After my page loads up, the whole section disappears.

Can you help me so that it stays there after it does the book load trigger?

I will provide two read-only link.
One is my current modified link.
The other one is the template default link.

Here is my public share link: **LINK **
