Invoice number not reset at beginning of the year

The invoice number was not reset at the beginning of the year as we have configured in Syste/Configutration/Order tab. We have to update manually the invoice number because it continues to calculate 00160/3/2017 and last invoice in 2016 was 00159/12/2016. Now we have updated last order to invoice id 14 and invoice number "00014/3/2017" but next oorder will generate again 00160/3/2017. What we have to update to get the system generate the right invoce number?
Thanks

Please check configuration in attachment

We are using HikaShop since 2014 and we had no problems with invoices until 2017 and after different version updates.
We know orders are not reset, just tell us the SQL statement to run to reset this number. Again, there is an invoice 159/12/2016 and we updated manually all 2017 invoices, we are sure next invoice will be 160/3/2017 .

Last order, this is data base data, the last order is 00160/3/2017 and the previous was updated to 014/3/2017

Another problem we found was the invoice date equal to order date. If the order is paid by bank transfer then is confirmed manually when we receive the money and print the invoice. But if we receive new orders then we have an invoice with a recent date and invoice number, when we confirm an outstanding order the date is old and invoice number new. This is not accepted by italian fiscal rules.
