Customer contact and job list

We use QBDT 2024. We use number and last name for formatting. For example job 101 Evans thru 999 Posante. When trying to add job 1000 and above it populates before our earliest active job 442 Monroe and not after job 999 Posante. We must use this style to differentiate between a new job for the same customer such as 300 Smith and 850 Smith #2. Also same last names. We use number/name for everything, from job creation to material ordering to subcontractor pay request to customer payment. I called QB Support last night and they turned over to IT Support. I have 20 new jobs to enter.
