25B Manage Bill Transaction Form - Adjustments not showing up

Does anyone have the issue of adjustments to transactions not showing up in the Manage Bill Transaction form? Below is the scenario we have observed:

1.) Time Card imported with a line of 7.9 Hours for 5/28 into PPM
2.) Time Invoiced. Bill Transaction shows this transaction as In Progress
3.) Timecard is corrected in OTL from 7.9 to 8.9 Hours
4.) Import Cost imports 2 lines to PPM; -7.9 to reverse the original transaction and the 8.9 for the correction
5.) Billing Transaction form shows the 8.9 Hours but does not have the -7.9. This is major issue as the form is showing the incorrect total that should be billed; the 7.9 and 8.9 Hours. It is missing the -7.9 hours
