Setspreads, replacing spreads


could someone maybe help me with something that might be a easy problem to fix. i am staring at it for hours and i cant find a way to do it.
maybe its something with spreaded binsizes, i dont know.

I have a source spread and i want to replace some values at certain points.

i thought it should be possible with setspread.

look at the image and file for more information.
