Why does this lesson never show up on the lessons tab?

Why does this lesson never show up on the lessons shelf?

I can get to it by going to the Courses tab and opening the Course and finding it and clicking on it.

But AFAICT all other lessons except this one show up under the Lessons tab.

Can you please try to assign a level to it and then give it another try?

What level would you like me to assign to it?

(I don’t use levels myself.)

Set it as Intermediate 2 level and let me know if it appears.

Ok, thank you, I tried that, and it does not appear to have made any difference.

Have you figured out why this bug is occurring?

@zorbital Can you please take another look now?

I tried again, and now it works.

Thanks.

Was it a bug that had to be fixed in the code, or was it a bug in the data for that particular lesson?

@zorbital Thanks for the update. It was an issue with that particular lesson and it had to be re-generated.
