I’m having the same issue. For some reason, the custom CSS isn’t being nested within the div for the widget; rather, the script is showing up before the div in the HTML, and it throws the CSS off for the remaining widgets on the page in a way that isn’t acceptable. If I drag and drop it inside the div within Chrome dev tools, everything sorts itself out, but I can’t figure out how to make that happen permanently (not sure if it’s driven by the theme functions php file or the scss). Not sure if that helps diagnose the problem.
