Passcode Requirements change

[Umpi21]

Good Morning.  We schedule a lot of Zoom meetings and let Zoom auto-generate the passcode for the room.  Today we need to change the date and time of an existing meeting (that zoom had auto-generated a passcode for) and it's saying that the passcode (that zoom auto-generate) does not meet the requirements.  It's saying that it can only now be an all-numeric passcode?
