Question on Chart B Rows 12 and 13

I jumped the gun and started, and now have a question. When I go from Chart B, Row 12 to Row 13, the "dotted" stitches (on the outer edges, both sides) do not line up. The overall stitch counts are OK though-and the inner dotted stitches line up. I have been putting my stitch markers in the middle of the two 'reversed' stitches, so this confused me. Also-on the pattern, they line up, but the 'extra' 3 stitches on each side on row 13 have to come from somewhere. Am I doing something wrong? It looks OK otherwise.
