I have a big concern as to why I cannot edit the home page on the Handle theme. I also cannot add any new pages?

I am trying to add in a counter bar plugin, and I can’t make a new row and add a plugin on the home page. It just seems like its not customizable at all. I then attempted to put in WPBakery to assist with this – but this also doesnt work.

Am I doing something wrong? The simple page editor seems like its not usable.
