If you're working the chart rows through a second time, you've probably increased the stitches on the edge. So then you'd work the beginning stitches, place a marker, work the repeat to the next marker (which you can leave or take out), then work either another repeat or the sts after the red box.
If you're still on the first time through the chart, then perhaps you did something wrong in the set up rows before this, or are still reading the YOs as using a stitch when they don't. Or something else....
It may be helpful if we can see the beginning rows to be more specific.
