Dawn inventory block show "Backordered" if stock = 0 and continue selling = yes

[ElkhoundDigital]

I'm using Dawn 12.1 and wanting the inventory block on my product page to say "Backordered: 3-6 week wait" with the color being orange. Right now it shows as "In Stock" with a green light despite setting show stock if inventory is below 3. 

Why does inventory being 3 and 0 both show the same stock message?
