I’ve set buffer stock, but why buyer still can purchase the product when it already hit buffer stock?

OMS (SelluSeller): This could be due to pre-booking promotion set in OMS (SelluSeller) for the product SKU where stock is inflated in the catalogue page in OMS (SelluSeller) and Marketplace.

Wareo: There could be the possibility of stock addition of 1 piece via stock adjustment performed.
