Need help with a CutSweep Feature on complex profile

Good day Solidworks community :-)

I am struggling creating an even CutSweep profile on this shape from a START end END Profile. What I want to do is a extruded slot with the edges deeper than the center portion.

I get this result with a deformed groove. I tried various option in the CutSweep feature but could not get it right. Any idea what I am doing wrong?

Thanks!
