Create a Custom Opportunity Compact Layout

I feel like Ive done all of the steps: 

• Create a compact layout for the Opportunity object:
  • Label: New Oppty Compact Layout
  • Name: New_Oppty_Compact_Layout
• Include these fields, in this order: Opportunity Name, Probability (%), Close Date, Stage, Amount, Opportunity Owner
• Make it the primary compact layout

Yet, I get the following reason that it isnt completed: Challenge not yet complete in Data Modeling

The 'New Oppty Compact Layout' compact list is not configured for the opportunity object.

I even see the "New Oppty Compact Layout" in the Compact Layout section of the Opportunity in Object Manager
