Hi,
I see you're using page "Custom Blog Page" to set it's your homepage.
Please go to admin page > Settings > Reading > and make sure your config look like this image - It will better more than with use a custom blog page.
After that, go to Customize > General Options > and un-check on "Enable Sidebar on Homepage" to disable sidebar on homepage.
I think you should check documentation for this theme here to know how to config this theme.
Best Regards,
