Automatic Sales invoice numbering

Hello, I need the sales invoice number to be sticky to “automatic”. I don’t want to check the checkbox everytime I create a new invoice.
I had created a company some year ago and it worked as wanted. Today I create a new company but the checkbox is unchecked. How do I turn this permanently on?

Best regards

Settings > Form Defaults > Sales Invoice

Thanks!
