Zoho Sites builder not showing the presets that we've created on our site

Hello Zoho,

We've been experiencing difficulty building our site, https://www.envisionlh.co.nz/. Every time we work on the back end and we make changes, the Zoho builder shows the wrong colors but once we publish it, the live site still shows the standard settings. We see different colors and fonts in the builder but when we publish, it follows the presets. We tried uploading a custom CSS but it didn't do anything. How can we resolve this?
