Themes on www.ads-software.com are not allowed to include demo content: https://make.www.ads-software.com/themes/handbook/review/required/#importing-or-downloading

Use your own content. It’s a theme. It doesn’t need special types of content to work, it should display any content correctly.

Personally, I feel that you wasted your time. It worthy if you ask support first.
You can explain or ask support https://www.ads-software.com/support/theme/vw-charity-ngo/
You can ask the theme documentation link that how it works but giving 1 star is not good to see for the very first time. I hope, you reconsider your review.

All the best ??
