Backend Order Problem

Hello Balbooa Team,

I am having a problem creating orders from the backend.

This particularly affects products that have multiple variations.
The problem is as follows:
When I place an item that has variants, I am then unable to place another variant of the same item because this item can no longer be found or is hidden.
This is particularly annoying when an order contains one product but several variations.

I hope you can help me with this problem.

Thanks and best regards,
Dominique
