Oh yeah, I see that. A green sample. Which sort of makes sense.

Seeing the green line makes me think, yes, it is the first copy, which
appears to be extraneous.
But what made me wonder is that in example #24 is the function key text
followed by a blank, thinking that it's blank because the mesh is
absent. And then there are a bunch of examples previous to that where
the mesh is present and the function key text has a sample line the
color of the mesh. I suppose in example #24 the text is also extraneous
and shouldn't appear.
I'll write up a bug report this evening with a patch.
