foreign currencies are shown as 0.- in default currency reports

[tereque]

I made a new file by >File >Export >Export Accounts

I am dealing with 4 currencies in my accounts USD, HKD, EUR, CNY
My computer's locale is US but my default currency (as well as my 
default report currency) is CNY.

In my original file's "Accounts" page and the reports all foreign (not 
CNY) currencie's are displayed as the equivalent value in CNY(showing 
"present CNY" in the Accounts tab)
Now in my new file all foreign currencie's value's are only shown in the 
foreign currency. The CNY values are set to 0.-

So what I need it that all currencie's values are shown in my default 
currencies equivalent in the "Accounts" tab as well asin my reports 
(which are all in CNY)
how can I get that working?
