I went and looked at the pattern and tried out the part you are talking about to see what was going on. I agree with you that there seems to be a problem. That 1st rnd that it tells you to repeat is the "place marker" row. If you try to work it as it is written it really messes things up. I believe you with need to change each K4 to a K6 on the first repeat you do and on the second repeat they will go up to K8.
I don't know how to report a pattern error, but that needs to be corrected.
