It doesn't show converted 4.608 x 2 to Steem, but rather transfer. Meaning you transferred out of your wallet as its not in your wallet again too.
Doing the maths, 9.216 SBD = 160.401 STEEM at market rate on the 16th when they were transferred out, guess what? This is the exact number of Steems, showing in your cashout. I will end it here.
