Hello.
You don't understand how internal process interact in Exchange. We don't manually process such transactions, while moving of ALL clients' funds have taken place automatically by one of our internal process. Successful crediting of your account depends on another internal service which can process only standard transactions.

If you don't understand what is a contract wallet, we have a special warning https://prnt.sc/hdnl7y

Moreover, Bitstamp itself has a similar warning: https://prnt.sc/gi4fw5
