This is due to missing exchange rates. If no exchange rates are set, Manager will assume currencies to have exchange rates 1:1 which creates impression of different currencies simply being added up.
You will need to go to Settings → Exchange rates and set them up but right now it is manual process. Wait for the next version which will automatically download exchange rates from the Internet. Then your figures will become correct.
(if you don’t see Exchange rates under Settings, you need to enable them by clicking Customize button under Settings)
Adding the exchange rates will change the values, but in the wrong way.
the values are not in the correct currency for conversion (2nd ~ 3rd circle)
the exchange rate created are not considered (1st circle)
I’ll wait for the update.
