ChangeDetection says Zatu product is In stock when it is on BACKORDER

[IceHelm]

My ChangeDetection v0.47.06 says this Zatu product (Onirim) is in stock

Zatu uses an availability text of 'Out of stock' when they don't have an item and are not ordering it in, and use 'Backorder' when they don't have an item but are ordering it in.

Could backorder be added to the stock js file please? I see that back-order and backordered are in the file but not backorder.

Thanks.
