Burnt after first session; should I continue with the Soprano Laser treatment? (Photo)

I had a test patch for the Alma Soprano Laser and had no issue. Six weeks later, I went for my first treatment. After my first proper session, I noticed I had been burnt on my bottom and bikini area. I have dark skin but opted for the Soprano as it can be used on all skin types. I was left a dark hard layer of skin / scab from the burn. I have been back to the clinic and they checked it and said this is uncommon. Shall I continue with the rest of my treatments or stop? Is the scar permanent?
