I'm sorry--I didn't quite get what you meant. I find, and I have no idea if this is the situation in this case, that sometimes when I am working on the back of a place where I have decreases and yos, that the k2 stitch gets pulled up around the needle a bit when I do the yo.
So on the next row, when I have to work into the yo, it's kind of pulled up over the top of the needle. I have to roll the stitch down on the needle toward me to reach where the yo strand actually is. Take a look at your stitches, and if it seems like the stitch part is up on the needle, roll it down toward you and knit into the strand that comes down with it. See if that helps.
If you have no clue what I'm talking about, and I won't be at all surprised if you don't, let me know and I'll see if I can post a picture, since the shawl I'm working on is having this exact problem.
