Hello @twoscotsabroad,
Thanks for writing to us.
I checked your site it seems that you are using any cache and JS/CSS minification plugin. I would suggest you purge all the cache, purge all the JS/CSS minification, and temporarily deactivate the plugin then check it again. I would also suggest you clear your browser cache as well or check it in the private mode of the browser.
I would also suggest you troubleshot a few common issues on this.
1.Plugin Conflict
2.Theme Update related issue
3.Child Theme Related issue
4.CSS/JS Customization
Hope it helps
Thanks
