I mentioned this to Olga at Linn Academy but I'm still having problems with this.

When I create an order for transferring stock to an Amazon fulfilment centre I can't split the packaging.

The shipment contains quite a few SKUs (maybe 10-15), split over 9 boxes. I make the split, check all boxes are within size and weight limits and click save but nothing happens, I have to cancel and try to make the split again. Sometimes after trying 3 or 4 times it finally works, but normally I give up and have to create the labels manually through the courier website

I have a video showing the problem if that helps..
