Unhide Standard Fields Functional Config Module

Just want ask, how to unhide a standard Field on Functional config(inventory Balance)

the field that  i want to add is the "totalGrossWeight" where in, this field is included in select query generated by this report.

We have restored back the “totalGrossWeight” field to Inventory Balance module in sandbox environment. The only way to solve this issue is to click on the “restore default” button at the Function Config as below. Once you clicked the restore default button, it will reset the page to default.

Please ask user to try right click on the screen and select menu “Delete Personal Columns”.  And check again.
