Need Advise on Pool & Spa grout bleeding

We just recently completed constructing our pool and spa. Our pool builder used Mapei (North American Adhesive) 4300 grout (Smoky Coal); non-sanded. We had the grout cure for at least 24 days. After we filled up the pool with water (no chemicals and the water isn't heated), and noticed that when you touch any of the grout lines, the pigment or color washes off. Our spa, in particular, is unusable because of this since you end up with black pigment all over your body if you use it. Our pool builder indicated that it may take a year before this stops happening...but I am looking for advise to address this. Will sealing help? I've attached a video to show what is happening. Any advise would be appreciated.
