Import Invoice: This error is related to Row {0} - {1}.

Hello,

I'm trying to import old invoices into Zoho Books.
On Thousand of lines I got few error messages I don't understand.

It says "This error is related to Row {0} - {1}."
!!!!! PLEASE HELP ME :(

Also I have other error like this: Item "Article 1" already exists
This I can read but I don't see why it's a problem....

Thank you
