Export for translation - Slide titles from title box are exported as untitled slide
Hello,
I came across bug when exporting files for translation. I sniffed something is wrong when I saw many "untitled slides" in my courses menus. All my original English slides are titled, but the title is mostly generated from the title box.
So I investigated and indeed, when exporting translation files when title is obtained from the built-in title box, the slide title is referred as Untitled slide. When you manually change the name to something else, it exports as intended.
You can see with attached .story file what happens when you export translation file.
And also, on the very bottom there is menu section. This is not translating menu at all, it takes titles for the menu from the slide title on corresponding slide. In this case it shouldn't be even present in the translation file. Can you please delete this in output? PLEASE don't change the actual behavior - it is good as it is, as it minimizes error output ;)
