Asset Category account changed after Depreciation

Hi,

we have two Assets in our system for category 420.B which Depreciation Expense Account and Bonus Expense Account wrongly mentioned as 6040-1010-0-0-0-0-0-0-0-02 and 6040-1010-0-0-0-0-0-0-0-02 respectively.

After running the Depreciation , we found that segment1 should be 6020 inplace of 6040. We changed the Depreciation Expense Account and Bonus Expense Account  as 6020-1010-0-0-0-0-0-0-0-02 and 6020-1010-0-0-0-0-0-0-0-02 respectively and re ran the depreciation again but the depreciation is still hitting 6040 account.

Is there any way the depreciation accounts hit 6020 and what should be our approach to rectify wrongly posted prevoious depreciation.
