Teared pricing does not work in dashboard

Hi,
i use teared pricing.
If I create an order in the backoffice/dashboard I can add a product,
but the price is not calculated new after modifying the quantity.
The system shows allways the highest price for quantity 1, don’t matter the quantity-input.
I even don’t can modify the price, because the price is not an field to edit.
Pricing in Customer-Frontend works correct.
What I have to do that the system will use the correct price in backoffice?
