Edit Package Contents use entered item weight
New products in WooCommerce don't carry over the item weight to Click and Drop.
For example: my 'New Item' is 20g, but my total package weight comes to 150g, after I apply postage it stores 'New Item' weight as 150g - the weight of the whole package.
If I go to 'edit package contents' and enter the 'New Item' weight (20g), BEFORE I apply postage, it still stores "New Item' weight as that of the whole package.
Is there a way of making it remember the correct weight?
