Nested Form not working

I have a table called Invoice that has a list of Payments. In the Invoice table, Payments appears as a list with the reference to the Payments table. The Payment table has Invoice set to ref and ISPARTOF. I have verified the data setup many times but the nested form is just not showing.

Under info, the map clearly shows that Invoices ‘can be made up of’ Payments.

Could the show_if for the VC be hiding it, per chance or maybe it’s not included in the slice?

Where are you not seeing the nested form? Can you provide a screenshot?

Fixed. But not really sure why. I originally had a unique spreadsheet for each table and recreated it with a single spreadsheet with multiple pages.
