How long for lisence # in maryland

I took my test on july 2nd I found out that I passed through pearson vue on July 4th. My name and LPN checklist didnt come up until July 7th and I still don't have a lisence #. I have found a job and was due to start on Monday but they said I can't start orientation until I have a lisence #. Is there something wrong or is this the normal waiting time. Please let me know how long you waited for your #, or what might be holding it up.
