I think this may be some formatting code that shows where it shouldn't.
* p next 3 sts tog, %uFFFD leave on needle, 0, k same 3 sts tog, slip off needle
I think maybe it should be: p next 3 sts tog, leave on needle, k same 3 sts tog, slip off needle ... but the 0 after leave on needle, seems to indicate something else should be happening. Working p3tog then k3tog into the same stitches then slipping them off the needle nets a decrease of 1.
I don't know how to enlarge the picture to see if that would help see what's going on.
