We are trying to build a theme from scratch using the builder. After adding CSS to a region container, saving the theme and exiting out of builder, the css code seems to stick whenever we check a page.
When we try to get back in, we can no longer see the code we created. There is however a physical file saved in /element-styles/region-container/single-page-2-main-content-style.css; but it seems builder is not loading its contents.
Can you please help?
