Act sent letter to my son wanting to cancel score

The 28 was not sent to all of his college choices he will be playing baseball and they’re are several colleges interested in him. So the first test we sent the 22 to 3 colleges and the 2nd test 28 we sent to 3 different ones. But since he is leaning more toward this certain college the school had to send his transcripts and act(28) but the college wanted actual email verification from act personally. So since then is why act sent letter saying concern of 28 not being accurate. So that’s why we sent in his school transcripts, he has never made a B and his gpa is 4.35 and act after reviewing his transcripts said academics didn’t prove good enough to determine 28. I just don’t understand.
