Hi,
These are not Private label products. So it has order different products in different categories which are shipped to amazon address as you can see below in a screen shot? Is it normal or what could be the reasons? or is Amazon doing DS 
Your precious feedback will help us to understand this matter.
Thanks
Raise your price Amazon will pay it!
They are dropshipping.
As @ahmad0 said.
They are advertising your products in markets you don’t sell and buy from you when they sell.
Win win!
They resell it to other countries.
The best part that is absolutely zero refunds with those orders.
They sell your products on other marketplaces if you don’t already sell there, essentially dropshipping; if third-party sellers do it, it’s considered a gross violation of Amazon’s policies, but if Amazon does it, then it’s allowed.
As others say, there are the best orders you could possibly get. If anything goes wrong. Amazon will just sell them through warehouse deals.
Thank you so much for the explanation
