I see - that explains. In that case, I think it would not do harm to let the schools know somehow, although it might be tad bit late now (best if your reference provider explained this rather than yourself). You don’t want to appear like a boxer who is afraid to step into the ring for the sake of preserving perfect record. Also, they may assume you entered those and did not do well enough to submit. I think you would actually love those contests and do well on them. For the SSAT math, absolutely nothing to worry about - a 97 and a 99 are the same.
