I have a SL course that looks find when editing, but once it's published, it scrambles the slides across the diff scenes. For example, I have 2 question slides at the end of each scene. But once I publish, scene 1 brings two of the questions from scene 2 into scene 1. It's not just question slides. One scene has brought in content slides from another scene. It does this in preview, publishing locally and on review. Everything is updated. Looks this way in multiple browsers.
