Blending issues with illustrator

I’m trying to make an inset shadow on an object in Illustrator. I’ve copied my original shape and then offset the path and then blended the two.

I cleaned up both paths before blending BUT i’m getting some weird corners in the blends. Bad enough that I can’t ignore them.

Anyone had this happen to them? Did you find a solution?

Here’s some screenshots of what’s going on.

Can you post a mockup of what you are trying to achieve? Do it in photoshop/fake it so we can see what the end result should look like.

From the description and the chopped up screenshot it is not clear what is going on, what is expected etc…

Do not crop… context is nice. YOu might understand the crop but we see chopped up pieces that we don’t comprehend and close the post and move on.
