None of these responses actually fix the problem. This has been going on for years. Does anyone know how to fix the actual issue at hand?

We created an item on 4/9/24 to begin tracking on 01/01/21 with 0 quantity. First purchase was made 11/01/23, first sale was made 11/02/23. Invoice says please select a transaction date that comes after the date you started tracking the quantity. Does anyone know how to actually fix this?
