Weldment Cutlist is incorrect (Help)

So I have designed a chassis for a trailer, but when i go to create a drawing the cutlist has merged different weldments together so my cutlist does not display properly. in the model you can see its merged/highlighted atleast 4 different types of material under the same weldment in the cutlist for some reason and i tried updating it which didnt change anything.
