adminhtml – Magento2.3 SetTemplate does not work for the first time with ajax

I would like to add additional information about the field in sales_order_create_index.xml
I used setTemplate:

            Custom_Custom :: order / create / data.phtml


If I create an order from sale> order> create order> select customer> go to the order creation page. There is always a model in the magento kernel.

Once I've reloaded this page or rearranged it correctly loads my model
Someone knows this problem
