I think you should report that to chess.com
my gripe with tactics trainer

I wish tactics trainer would take into consideration ones present rating when it offers a new puzzle to solve. By this I mean ,if your rating in Tactics is 1700, why give one a puzzle rated 1200? I feel that there should be a 200 plus or minus bracket based on ones present rating. I am complaining about this simply because I have difficulty solving the lower rated puzzles.
It does, but the ranges are pretty large.
