Does the actual pdf reflect the changes when you open it. The 990 that I tested did give a rather goofy looking pdf file name. I would simply open the file and select save as. I have a pdf editor that allows me to have with the password. If support can't help, then I am not sure that they understand the problem. Maybe @IntuitAustin or @IntuitBettyJo can bring it to their attention and help to get this annoying "unexpected behavior" enhanced.
