How do I pass the "Create Custom Picklist challenge" on get started with picklists?

Link to module here 

Task is here:

You work for a cookie store. You sell lots of macarons. What’s a macaron? A macaron is a cookie that comes in many flavors. So, your customers have a lot of choices.

• Add a picklist field to the standard Product object with the following settings:
  • Object: Product
  • Field Type: Picklist
  • Field Label: Macaron Flavor
  • Field Name: Macaron_Flavor
  • Make sure Restrict picklist to the values defined in the value set is selected
• Include the following picklist values:
  • Gingerbread
  • Strawberry
  • Chocolate
  • Raspberry
  • Pumpkin
  • Mint
  • Vanilla
• Make this field visible to all user profiles

Basically,

I've made the custom picklist, entered all the necessary values (the macaron flavours) ensured visibility to all users - ticked visibility box up at the top & read only as well, and yet when I click "check challenge" the validation fails. i've looked up other articles on case sets related to picklists and it didn't help pass the challenge, so what else do I do?
