Two home pages

Hi there! I thank you all for the support you can provide. First of all, I apologize for my English.
I’m making my first WordPress site and having a lot of difficulties.
The worst of them is that I have two home pages (the one I created, and want it to be my home page) and another one that wordpress created itself. I dont know if this is normal but this page doesnt shows in “pages entry” inside wordpress admin (so I cant delete it).
If it helps I use DIVI.

The page I need help with: [log in to see the link]
