You have enabled the question "Do you want to enable automatic proposal of posting date based on system date?" under Group: Enabling automatic proposal of posting date in Italy

Therefore you expect the Supplier Invoices posting date (for Italia Suppliers) to be today's date (system date).

The system will apply System Date for posting date when the buyer will be from Italia.

This is is the expected system behavior.
