When I insert an invoice for a client with a past date (with Invoice Manager) this gets recorded in Expense manager with the date of today, not with the date of the actual invoice.

Let's say today is the firsth of february and I inserted 10 invoices for january. When I go to Expense manager and I filter from 1 jan to 31 jan I don't see the income of january because their date is the firsth of feb.
