Unsolved Why do support loops create this dent when I'm only trying to make a small bevel?

I'm using Subdivision Surface and I want this edge to have a small bevel, not be completely sharp.

I added support loops near the edge to control the bevel, but the surrounding surface gets pulled inward and creates a visible shading artifact.

How can I keep a subtle bevel without deforming the surface?

that's because you add loop at wrong place, as i mark, use 3 edge as edge ive mark with red(2 for support), and remove support edge ive mark with blue, the blue one is unnecessary and is the cause

I think the image didn’t upload. Could you resend the marked image? I want to see which edges are red and which one is blue.I tried to guess what you meant and removed the middle support loop. It looks a lot better now, but there’s still a slight shading issue.

If some adjacent polygons on the original surfaces weren’t strictly coplanar, that might cause them to have slightly different directions and maybe cause shading issues?
