The adjustment of posted project transactions behaves incorrectly after enabling the "Multi-select posted project transactions for adjustments and credit notes" feature. Specifically, all existing transactions that have 0.00 cost are displayed in the adjustment form together with the transactions that were initially selected for adjustment. In addition to that, the performance of the adjustment process is significantly degraded compared to when the feature is disabled.

Currently (version 10.0.39), the issue occurs when adjusting Item transactions only. Previously, the problem affected Expense transactions as well. However, these have been fixed during release 10.0.36.

This idea is opened to suggest the same fix is applied to all relevant transaction types.
