Can not see GL in FBL3N report

Hi Experts

I am not experienced in SAP FI, right now user is running FBL3N report for Company code 6280 and wanted to check Trial balance = 0.

I can see in F.01 report the Trial balance =0 but in FBL3N report it has differnce of amount for 1 GL - 705000  in each period

We found that Line item display is not checked in GL master data and i guess the issue is because of this..

But when I tried to modify the Line item display then it still does not include GL,

Is there any standard steps to modify the config for this ?

Appreciate for your quick help , thanks!!
