Yes this would be expected.
For the fiat amounts to be displayed the exchange rate to BTC must be available via an exchange rate provider.
Realistically I do not know how soon I can add CryptoCompare but I will make a note of it.
It does look very cool since it carries a lot of coins, so thank you for suggesting this.
In the meantime, if you have PHP skills and wish to implement yourself some quick hack to pull clam exchange rates from somewhere, here is some boilerplate code that might help you:

I will try to get CryptoCompare added soon.
kind regards
