On backorder problem

Hi,

Before it worked well but since 2 days when i have a product that I sell even if I don’t have it in stock the sheet shows “on backorder”. It’s fine when I’m on 0 but sometimes my stock is -1 or -2 but it still shows “on backorder”. Please how do I do to shows the exacte number even if it’s miness something?

Thank you very much.
