Currently, if a liquidity journal has a currency set (e.g. Bank) the amount_currency shows lines according to the journal currency, which is correct. However, if the journal currency is the same as the company currency, the amount_currency shows the amount in the foreign currency that is not in fact held in the Bank.
Should be: follow the same logic for liquidity journals that have the same currency as the company (or set company currency by default) and show amount in journal/company currency.
