How to change the default tab to Lines when opening/editing AP invoices?

When I open an invoice, or edit an invoice, the system opens into "Holds and Approvals." Does anyone know how I can change this to default the opening into "Lines"? This is extremely annoying and I have no idea why this happens. I've seen similar issues with POs and was able to use a sandbox to change the default tab but that trick doesn't appear to work for invoices.
