How it used to work is even if you tried to apply postage to multiple orders at once it would add them to a Batch and let you individually select postage for each item in the batch even with mixed orders (International/Domestic)

But now when a batch is created with a Mix of International and Domestic orders you can't apply postage at all, for any orders!, the page's web elements break and a lot of them aren't loaded anymore, including the platform image.

Its pretty obvious some of the code is erroring out before everything can be loaded. Please fix this? This is pretty big in deciding if I continue to use Royal Mail. International Orders are around 50% of my orders.
