[1.6.3] Wrong Currency Amount Conversion

My standard currency in the app is EUR, currently living in Japan therefore usually entering expenses in JPY. When entering an expense in USD (e.g. Online transaction), the amount converted in JPY is displayed underneath. So far so good, but in the overview the amount in JPY is 1:1 displayed in EUR, so an expense of 30.000JPY is displayed as 30.000€.
