Campaignbuilders "Request Dynamic Content" asks for "not Campaign based" DWC by default

In campaignbuilder I can choose the decision “request dynamic content”
The popup that opens shows two fields:
Select Default Content is a dropdown that show only campaignbased DWC
Requested Slot Name is a textfield that asks for a Slot Name

I would expect that the slot name can be found in the overview of DWC items.
However, the Campaign based DWC items do not have a slot name.
When creating a DWC item and enabling “campaing based” the option to enter a slotname disapears

I tried to enter a “not campaign based” slotm but that didn’t render

So what is the correct thing to do here?
