Adjust Cost Post to G/L Posting Date Issue

Dear NAV Expert;

I'm desperately seeking for solution.
My client system NAV 2009 (R1)
All Items Costing Method setup as Average
Adjust cost Post to G/L setup to run every night (Nav Job Queue)

The issue is, user have posted Negetive Inventory Adjustment on March 2023, on the same night Cost Adjustment was partilly posted to G/L. The remaining Cost Adjustment was ported to G/L eight month later in Nov 2023. The finance team need explanation on this behavour. Question is why NAV did not pick up entire Cost Adjustment post to G/L on March 2023?

Thank you.
