Customize colors not saving.

Hi there,
I’ve been working on my website on the Highend Theme. I’ve tried many times to try and change the various color options of the theme, but the changes don’t save. For example, ill change the accent color and you can see it change on the edit preview. I hit save and publish. Then when i go check the site, it reverts back to the original colors. In the pic attached you can see the color of the top bar and bottom button have changed. When you preview top bar is white, and bottom button is bright blue.

I read that people were having similar issues and it could be related to plugins, so i deactivated them to see if that would change it and it didn’t.

Any help or suggestions would be great!
