I have been doing the show crew function for my own flights though, so maybe thats why it works? It possible its only for flights assigned to the pilots profile, but IDK. Ill try some random flight and see if it works still.

EDIT-- Yes, that appears to be it. I stand corrected, "show crew" is only working for stuff on your schedule. I can only get it to work with those flights. I apologize. Maybe its an error, and its an easy fix by IT as its not the same as showing in open time, but its a start.
