Storyline does not export complete project

Hi, I thought I'd try it here before I do unnecessary work: I'm trying to publish storyline scenes that are saved in one storyline file to Review 360. I want to avoid having to publish each scene individually (it's more than 20 and would take quite long), however when I publish the whole project, it only publishes the first scene. I already tried to import the scenes into a new file to exclude any bugs in the file, but the result was the same. Any idea what the problem could be? Thanks so much!
