Plugin breaks my full-width layouts for some reason

Hi again,

Great success with Flying pages, but I just tried this one and it breaks my ‘alignfull’ sections.

I’ve deactivated the plugin for now, but if you can follow up with me on email, I can provide screenshots or a login for you to see for yourself!

As soon as I activate it, the layout breaks, even if just using the native option.

Thanks,
Lyden
