Doing inclusive split, gives default result

Hi,

So now the select split is working.
But now it is not splitting according to my general settings. It is only splitting like the Default split. I am trying to use “Inclusive” which means the selected items should end up together in 1 order right?

The settings I used:
Setting to inclusive
Select products that are used for inclusive 1
Select products that are used for inclusive 2
Select products that are used for inclusive 3
General settings for splitting order

How I split:
The items I selected to split

The result of the split:
The result I got when splitting the order
So here you see the two items I splitted are splitted in two separated orders. They should be together when using inclusive right?

Best regards,
Olga
