Supplier invoice number uniqueness

ERPNext
1

Hi, during the end of year check of my accounts i identified 2 double invoices// invoice entered twice.
I than checked the supplier number which was identical.
This used to be impossible. One would get a warning and could not submit.
Is this feature removed or does it not work properly??

@becht_robert, in Account Settings, disable the option to check the uniqueness of the Supplier Invoices.
