The first one is the Casino Fees on the withdrawal and the second one is the blockchain fees for the transaction. They charge only the casino fee and they cover the transaction fees.
They keep the remaining $1.4 and this is not new, all the casinos and exchanges do this.
As we can see in their TOS:
Note that some payment methods may include an additional fee. In this case, the fee will be clearly visible for you in the cashier.
And I see in the images there was the warning about the fees, so, they didn't break any rule.
