@San_Thida_Myo_Latt, you need to more completely illustrate what you think the problem is. Show the Edit screen for a transaction you think is not being reported correctly. And if you are still running v20.2.88, show the report you believe is correct.
@San_Thida_Myo_Latt, you have not provided the requested information: no Edit screen for any transaction and, after obscuring most of the report the first time, nothing from v20.2.88 at all the second time.
Can I suggest that you amend your custom report by removing the selection lines one by one starting with line 4, then 3 and 4, then 2,3 and 4, etc to see if it is caused by one of the selections
@San_Thida_Myo_Latt, based on your screen shots, the custom report definitions are not the same. The second shows no “Group by… Supplier | Name”. Did you simply fail to capture that?
