I have 3 VAT codes on my invoice.

Each VAT code has another sequence number.

The system is calculating each line properly, but always selects the first VAT code for creating the posting. 

The overview shows the total amount correctly, but it only considers the  VAT code of the first line and not the three of them. So, I am expecting 3 lines for VAT and the system is only giving me 1 line.

Am I missing something in the configuration?

I am using odoo.com
