Menu title not working correctly

Hello,

I am having a problem with the Storyline menu.

I have a course built in Storyline with numerous scenes. When I name a scene, it appears in the menu in bold. This is by default, I'm not changing it in any way.

However, for some reason, my final scene, named in exactly the same way as the other scenes, is not appearing as bold in the menu.

Does anyone know what I'm doing wrong?

Thanks
