You may find that the logo in your Storyline course shifts up and to the right when you preview or publish if all the following criteria are true:
- You added a logo to your Storyline player.
- You saved the player, so it could be used in other projects.
- You applied the saved player to a new Storyline project.
This is a known issue. Here's how to correct it:
- Go to the Home tab, and click the Player button.
- Delete the current logo from your player.
- Insert the logo back into your player.
- Click OK.
