Knot stitch with 3 stitches

I’m making the Blue Sky Alpaca Knot Hat. When I do the knot stitch with 3 stitches as called for I end up with an extra stitch on my needles. Any ideas for what I might be doing wrong.
Thanks in advance!

Link to the pattern? A few lines from it posted here? What are they telling you to do?

Thanks! Just figured it out!!
