Small amounts but anyway I'm absolutely sure I did not create these invoices.
Either the above or the correct password isn't provided, both will result with unpaid invoice.
But since you've mentioned that you didn't created those;
Have you at least tried pay the indicated address but failed to type the correct password or left it blank?
If not, someone has direct/remote access to your machine but (
fortunately) do not know your wallet's password.
If yes, that's normal as I've explained.
