Prestashop 1.5 Delayed Shipping Not Working

[scandbev]

Hi

 

I am having problems getting the delayed shipping to work in my shop running verison 1.5.3.1. The tick box is visable but nothing happens when I put both items on stock and out of stock on the same order. One order is created instead of two as it is supposed to.

 

I'm using the follwing settings:

 

Under orders:

 

Delayed delivery -  enabled

 

Under Products:

 

Allow ordering of out-of-stock products - enabled

Enable stock management - enabled

 

Finally the tickbox "Send available products first" when finalizing the order.

 

Would very much appreciate help on this. Hope there is someone out there having a idea on where to start the troubleshooting or even better  had the same problem and successfully relsoved it.

 

Regards

Peter
