Can't fill data inside array inside an array

Hi,
How can I add data inside an array of an array ?
No fields appear when I want to fill my data inside.
I can only add an empty field.


As you can see, there are no fields but only the button "Add pole_cities".

Thank you

No file, test, or entry point is identified in the report. Reproduce the nested-array editing case in Amplify Studio using the attached screenshot as context; done means fields appear and data can be entered instead of only an empty nested item.
