Sheetmetal Bending, Sketched Bend Issue

I am current having trouble with the sheetmetal sketched bend feature. See my current part below and the line which I want to bend it highlighted in blue. I only want the part to bend on this line with the fixed part being the larger portion to the right, however it currently also bends and curls of the "hook" part of the design, see photo below. Is there a workaround to bend the shape as shown in the third picture below while still utilizing the sheet metal bending feature and maintaining my geometry. 

Thanks,

T
