I configure my Odoo with this indication here:

https://www.odoo.com/documentation/user/9.0/accounting/others/multicurrencies/how_it_works.html

and read : But there are now two complementary fields, the amount that was actually paid and the currency in which it was paid.

BUT on my instance I never can see this two fields. Neither on account bank statement current or when create a new account bank statement.

My Odoo version is :

version 9.0c-20160620 (Community Edition)

How can I do to see this fields ?

Thanks
