2LIS_11_VAITM has incorrect net value

Hello Experts -

There's a sales order document in Production with 3 line items: item 10, 20 and 30. Lines 10 and 30 have the same material number. Then line 30 was cancelled. So now there are only 2 line items: item 10 and 20. However, the net value for item 10 is the sum of net value of lines 10 and 30 even after cancelling line 30.

Has anyone seen this before? If so, what would be the solution?

Thanks!
