Discripency in inventory adjustment value and FIFO cost lot tracking report report

In zohobooks, I have added 200 bag of itemA with unit rate is Rs.1408 as opening stock on Apr01/2025, after that i make a inventory adjustment for 100 bag that I transfer to stock in process account, after that I make a purchase bill for the same item on 20 April, what my problem is Inventory adjustment by quantity that i made is supposed be calculated based on the unit rate that i mentioned in opening stock, but it calculated unit rate based on the purchase that i made in 20Apr. how to resolve this issue?
In FIFO cost lot tracking report it shows that adjustment quantity is reduced from the opening stock, But actually it reduce from the purchased item on 20April
