Hello,
My message :
In the first image you're opening the main order ; the one that the customer can see and which display all products (for all vendors).
The second is the vendor subsale ; which contains only the vendor products.
Best would be to open the orders in the HikaShop backend to compare the results.
Opening the vendor order without the details of the corresponding main order, does not provide any information that we can use.
I did not tell you that a customer can see the content that your super-admin would ; I told you that the super-admin opened the content of the order related to the customer ; while the vendor display something different from the database.
So you're trying to compare elements which are not coming from the same data.
That's why if you want to solve it, I highly recommend you to open the same order (and the "order_id", not "order number") in your backend in order compare the content and be able to understand what is going on.
Regards,
