Split lessons missing audio on last part

Steps to reproduce:

  1. Add a lesson + audio where the word count of the lesson is greater than 4000 words
  2. Wait for All parts of the lesson to get added to your course
  3. Verify that all parts of the split lesson contain audio EXCEPT for the last part

Thanks. I noticed that problem too. We will look into it.
What you can do in the meantime is just to cut text from last part, then copy it to previous part and save it, since the complete audio exist in previous part.
