Table Rate Shipping Does Not Work For Multiple Items

I can’t seemed to get the Table Rate Shipping to work for multiple items. The shipping shows up when I added 1 item to cart. But when I added to two items it says shipping not available. I use the weight for shipping table. Min number is 0. With lots of different weight tiers. So i.e. 0-1KG, 0-2KG. With different zones of shipping UK, EU, and everywhere else. Please find attached my screen shots.

Please can you advise what to do to get it to work with multiple items?

Many thanks,
