Problem or Misconception. Please help with Multisite

Hi,

I paid someone to install WP multisite domain mapping.
I am so confused as after I added my site https://www.247foods.com to the domain mapping, when I click view, I will get https://247foods.skincodes.com/ (with no contents)

While when I click https://www.247foods.com, this one has content.

Now which one is my site and which should I promote.

Who added content to https://www.247foods.com and who is it making money for.

Please claify
