I appreciate all the details you provided to sort out this matter, @chaneymillerinc.
Re-categorizing these transactions will affect their posting including the details shown on your report. That said, this could be the reason why the job you had re-categorized is showing a credit amount.
On the other hand, we can open that transaction to review why there was a credit. If this is an invalid credit we can delete and recreate the job and post this to the correct category.
