Use Center in Hoop (Home tab) to move the embroidery to the center of the hoop and, if necessary, add a hoop movement so that the embroidery starts from the center of the hoop.
When an embroidery is not centered, it may be difficult to repeatedly stitch out the embroidery so that the stitchouts line up. This may happen with certain embroideries that have a start point at the side. Use Center in Hoop to correct this.
