Issue with the accounting entries for Acqusition Cost Adjustment for Cost Org with Std cost method

Summary:

The Acquistion cost adjustment triggered twice i.e. with positive & negative qty.

We had a scenario where the PO Price Adjustment were been done where the PO Adusted Unit Price > Standard cost for 10 qty. Here all these 10 qty. were received.

The Acquistion Cost Adjustment created with 20 lines. 10 for positive qty (1 unit each) and another 10 with negative qty(1 unit each on each line).

Can you please confirm the why these reversal entries for Acqusition cost adjustment got triggered with negative qty?
