Hi @thewayback, I am glad to hear it is working now for you. About the issue, one thing it could have been, is that empty sections or containers, that you apply a fill color too, will not show up in preview or published mode, unless there is some height value given in the styles panel. I cannot say if that was the issue, but I have seen that happen before. In the design mode, empty elements have "height" so that you can view the elements in the design view, but if the elements are empty when you preview or publish, then the elements will collapse and have no height, thus it may appear like they are not visible.
If you have any further issue, please let us know, we are here to help
