Damaged sidestay

While stepping the mast on my DSIII the forestay got caught up with one of the sidestays resulting in the sidestay getting a curve in it as it wrapped around the forestay. The sidestays were already connected to the chainplates. I lowered the mast and straightened the curve in the sidestay before stepping the mast again and adjusting the tension. However I now have approx 3/4" to 1" section of the sidestay where the outer wires are no longer tightly wound. The inner wire looks ok. I managed to sail with it like this.
What are my options? Is there something I can do to get the outer wires in this area tightly wound again? Can I leave it alone and still sail like this. Or do I need to replace the sidestay?
