Normal/Shading issue

Hi,

I've got this weird issue going on with that edge right there. The normals are supposed to be smooth, but they aren't.

The vertices are definitely weldet, there's no doubt about it. modeling wise (when for example using chamfer, turbosmooth or moving vertices), the edge also behaves as expected. But the edge remains unsmoothed.

All faces in the picture have the same smoothing group.

I used the edit normals modifier and unified the normals, but the shading still isn't smooth:

I also tried a bunch of other things like collapsing the modifier stack, converted to editable mesh, converting back to editable poly, attaching the mesh to a fresh cube, deleting facing and bridging them again, but nothing helps, it always looks like this.

What can I do about it?
