Title field on sales invoices

I may be looking in the wrong places. But I can’t find anything in the Wiki or Forum explaining the last field–Title–on the Sales Invoice editing form. I have made test entries, but they don’t appear anywhere on the invoice. What is this for?

Not sure, could be it one of your custom fields (if you are using that feature)?

Post screenshot how that field looks like on the invoice form, that will make it a lot clearer.

You were correct. I had created a custom field called Title, but then turned off Custom Fields and forgot about it. Despite Custom Fields being inactivated, the field that was created still showed up on the Invoice form. Now that I know what was going on, I found several threads about custom fields and understand they are presently just informational and don’t appear on the forms when viewed. Thanks for your help.
