What’s happening?
Invoiced negative progress billing rules can cause a mismatch in contract values and total on-account transactions, leading to errors in the revenue recognition process.

Reason:
When a progress billing rule is created on a fixed price project contract with a negative contract value and then fully invoiced, it results in an incorrect availability of the reverse contract value for future invoice proposals. This behavior differs from when the progress billing rule has a positive contract value. Additionally, if the user selects the billing rule with the reverse value, creates an invoice proposal, and then deletes the invoice proposal, an erroneous extra on-account transaction is created, which cannot be reversed.

Resolution:
This was reported and fixed in D365 Finance version 10.0.43. Here you can find more details: Details for issue 963693
