Section Titles no longer centre aligned

Hello, RE: https://sloaneranger.com.au For some reason, the Header Media, the Gallery, and the Main Content section titles have changed from centre alignment. The header media on small screens has been pushed left The Gallery section title is now left aligned The Main Content section title is left aligned also I checked the CSS via Inspect Elements and from what I can tell, the titles are centre aligned so I'm unsure what is making them align differently. Thanks, Danielle
