UI Designer - Why I'm getting the wrong business data model?

Hey guys,
I created in the past 3 tables that are accessing the business data via external API and it works. Now I added a new business data model, called "Druckfreigabe". But as soon as I try to get my Content via external API, I get the old model displayed. That doesnt make sense.

I used this line for my old buisness data model, called ManuskriptEinsenden:
../API/bdm/businessData/com.company.model.ManuskriptEinsenden?q=findByStatus&p=0&c=10&f=status=pending

Now I want to use the new business data model, called Druckfreigabe:
../API/bdm/businessData/com.company.model.Druckfreigabe?q=findByUserId&p=0&c=10&f=userId={{session.user_id}}

And it shows the Manuskript-Data-Model-stuff. Why?
