Nodes 4272 4273 should be corrected by Detailed Correct to Line created by nodes  4272 4273 .

That is it.

Thank you very much.

So was this error created due to the meshing creating two nodes that were not exactly on the line?

And it can be corrected using the "Detailed Structure Correction"?

What alerted you to this error or was it just experience?

As I said, yes.
