CSD Unit 3, Lesson 21 Bubble 18, 19 and 20 - Can't see student code

My students are in Lesson 21. I am reviewing their work - see all of their code fine up through bubble 17.
On bubbles 18, 19 and 20, I can run and play the game, but the code is not displayed.!(upload://jLgHjv74eVSWXQkhsICHSVkLUE7.jpeg)

Hi @andrea.burgess,
Without seeing it myself, it’s hard to say, but it sounds like it may be a bug. I would recommend making a bug report for this. Here’s a support article on starting a bug report if you need it:

I did open a bug report as well.
Thanks! :blush:
