Problem with exchanging XRP into USD on Gatehub

[Invest2Day]

1.  I have 942 XRP and want to transfer it into USD.  When I go to the exchange it only lets me transfer 892 XRP and keeps 50 in the wallet. I believe this is normal for Gatehub but if I am wrong and there is a way to get that out please let me know. 

2.   When I am trying to transfer the 892 XRP into USD it seems to not calculate it correctly. As of this post XRP is at $1.16 but it only shows $826 on the USD side.  I would think it should be 892 XRP x $1.16 = $1034  

Is it fees that make up the difference or am I not looking at this right. Thanks for any help!

You should use trade to convert your XRPs into dollars. You get lousy rates with exchange.
