Using the 'Edit Site' toggle along the top, turn on Site Builder. Then proceed to clicking 'Edit Page' from the options that have appeared. Remove the Page Title widget and you should be ready to go.

Thanks for your help shadow, I can't remove the title widget as it says:

"You cannot remove a system module from the page template."

however, I think this is a bug.

I have removed the Page Title widget for you. In future, if you are editing a system template, you must set 'Overwrite Template' to 'No' and give it a name. Because your homepage is now using a non-system template, you can overwrite it freely now.
