Do you think that choosing the more information about this transaction is a red flag for paypal?

I highly doubt It.

You're simply viewing the transaction details.

Seen several comments across other forums where paypal seem to be very flexible and understanding that the seller did not have all of the required documents. Which seems hard to believe.

PayPal Is pretty strict when It comes to requesting and verifying documents, so I doubt that's the case.

To clarify about choosing more information about this transaction. It is one option out of three, the other options include providing either an invoice or a receipt for paypal. With the choosing more information choice, there is a free text box as well as an option to add a document but you can submit it without a document. So all in the all the easiest option.
