"There is however a two week period which is require to convert steem cash to steem and it does not show that balance in the wallet?"

right.
once you converted steem Dollars to Steem you have to wait about 1 Week ! and you cant see it in your wallet till the converting finished.
(by the way, if you would simply sell your steem dollars on the exchange you could get it instantly)

When you got your steem you have the decision to power up or selling for Btc for example
