Hello, @AshleyW,
I don’t see any issue on the site I have checked the shop page, and categories pages here are the screenshots of all those pages you can see here: https://postimg.cc/ZB1XLp03 and https://postimg.cc/tnpNy4Mw and https://postimg.cc/R31TYtPK also I have checked your issue by login and here is the resulting image: https://postimg.cc/k2TJvYCb it appears just fine.
So this seems to be the cache issue only, If you have any server cache then please flush it and disable it for a while and then remove your site cache and deactivate the cache plugins and finally check back your site after removing the browser cache. I hope it will work for you as well.
Regards 8Themes Team.
