So Rudi,
Please correct me if I was wrong. You're saying that all the calculation is correct, only the display is not?
So let go back to my test for example:
Meaning that after 7 Feb, the listing is still active until 9 Feb?Step 6. Apply plan: 3-day
7 Feb - Incorrect. Should be 9 Feb. ( 6 + 3 = 9 )
