Why does my sketch remain all blue in the clamp Exercise: Completing A Master Sketch

Upon completing this exercise, my sketch has one degree of freedom. It still operates with one degree of freedom between the two arms, which seems to be what it ought to do. Also the outlines of the two arms are blue, not black. But the completed exercise has the outlines in black and is fully constrained so it cannot be manipulated to show relative motion between the two arms. What's going on? I have shared my document with Onshape support and at https://cad.onshape.com/documents/65adec9951d00ffcf1c95028/w/cdc9bdb86808ebb343329f4c/e/b8fbfc2d140a530b6c6da5c8?renderMode=0&uiState=66dece10c6b90f54fd2d4fad

Hey Doug. Can't get into your sketch to see what's going on. Please make your document public. - Scotty
OK, see if you can get in now.
I think I found the problem. The completed sketch (answer) is wrong. It has an extra horizontal constraint. See screenshot. To be correct, the sketch ought to show a dimension defining the gap between the long and short arms.
@KatieHuffman This should be fixed in the Exercise, because the sketch is used later on to extrude actual clamp parts.
@doug_blanding I just went through the exercise and it's correct. If you look at step 5 it does say those points should be horizontal.
