Given the context and the baldly political direction behind the redactions, it's not at all unlikely that this is the result of deliberate sabotage or malicious compliance. Bondi isn't blacking these things out herself, she's ordering people to do it who aren't true believers. Purges take time (and often blood). She's stuck with the staff trained under previous administrations.

Or it is just the result of firing people who were competent and giving insufficient training to people who had never done this before.
