Strzok DENIES he was served and accepted a subpoena to appear - this will come up again.
I'm guessing it's some technicality... the Strzok type is known for this type of hair splitting... he WAS subpoenaed but not for this particular 'time' or some such 'exception' and in his mind negate this essence of the question. He's a horrible person. But your right - I hope it comes up again... it's shows him for the type he is...
