Landed costs - Over/under delivery transactions

Hi , i am try to simulate an overdelivery transaction in landed cost module in F&O; however it does not work.

I setup the system to has 100% as tolerance in over/under tolerance screen in Ianded cost module.
I have created a voyage that contains a Po with one item that has 1 unit . i posted the voyage so i can do the goods in transit (GIT) receive of 2 units. when i checked the Ovre/under transactions; the system does create a line that show me 1 unit that is over. However the status of that line is still in process which is wrong as i should see “completed” instead of “in process” for this line as the 1 unit is below the acceptable tolerance.
So what am i missing in the configuration??
