Rouge Recent Posts Widget on one of my pages!

Hello, on my WordPress site I am setting up at https://mmagloves.org.uk/
I’ve just selected one widget which is the recent posts widget but I have renamed it ‘Menu’ through the admin GUI.

This has been applied to all my pages but one – the home page.

The home page is displaying a widget called ‘recent posts’ on the right side bar which I don’t want. The renamed ‘menu’ widget has been pushed righ to the bottom of the page. The other pages seem to be ok.

How do I get rid of this widget?

Thank you.
