Can't edit my site on Website Builder

sellyourhouse.000webhostapp.com This is the url and when you look at it, it looks great - exactly what I want(published) but it comes up as a different when you click website builder to make edits. Please help. The site that is published is what I want but I just want to make a few edits.

Can you screenshot what you see when you use the site builder option?

I’ve checked the site builder myself, there had been no site created with it.
I checked your file manager and it is a custom uploaded website with files.
You’ll need to download, edit and upload these files or ask your website developer to do so.
