Webflow serving images that are way too small when published

Hi! I’ve been using the Agencia webflow template to try and get my site up and running. I’m having a problem, however, where whenever I publish the site, the CMS images (particularly on the homepage) keep on displaying at a size that is way too small, despite the fact that they’re coming up fine in the Webflow editor. Not sure if this is because of a setting I’ve accidentally tampered with, I’m bit of a Webflow noob. Any help at all would be much appreciated!
