Training not increasing skill on fast trainer but it shows it did...

OK, picked up a nice fast trainer and let him sit the bench a few seasons. He's at 1 pct.on some gray and white skills. When I train him, it says the 1 pct. skill updated on the training screen but on his profile both the gray and white skill are not increasing. Are the hidden but increasing???? Any idea what's happening? This may explain why I have seen so many good defenders with all 1 pct skills disarm and tackle my AMC that is 180. Had a guy last season that I ran into. All defenders at 1 pct skills that were so good.
