Level 3 Step 6 - no custom reprompts seen

[sheepworrier]

I followed the instructions and expected to see the custom reprompts:

'Which color would you like to hear about?'
'Please say the name of a color. Sorry we're having trouble. Let's try this again later. Goodbye.`

However, instead I only see the standard repeated 3 times:

Sorry, I couldn't hear what you've just said.
Hi again, {my name}. What's your favorite color?
