There is a 1% withdrawal fee. Which means you are probably missing the 3000 BTSX transaction. (3000 - 1%= 2970)
I would go to the console and type command to look at the transaction history, see if it is really missing. Sometimes the TITAN might screw up and due to privacy you won't see transaction details, but it will still be accounted for.
Contact BTER if it still is.
