AP Score Delayed Code 93

It’s been three weeks since I haven’t received my AP Seminar score and it has a code delay of 93. Can someone please explain this to me?

AP scores may be received later due to missing/inconsistent information, late testing, or special circumstances on test day. Nobody here can give you any more specific information, so call the College Board.

My son has two scores that are delayed with two different codes and calling AP didn’t help. They have been unable to provide us with any explanation other than call back in September.
