Update User Titles and Ranks
It counts down "User IDs". Take a look at it closely you will see that deleted users are not in the count down.
To Check:
You can also create two new users from the admincp and inspect the new ID's.
Then delete the first user you created, re-run the command, and you will notice it is not in the count down.
So you do not have an actual problem here.
