Magento 2.3.3: UPS shipping missing input fields (User-ID and Password)

In our Magento 2.3.3 installation I am not able to input the credentials for UPS shipping as described here: [https://docs.magento.com/m2/ce/user_guide/shipping/ups.html][1]

There is no input field for “User-ID” and “Password” as in our old M. 2.1.7 installation. Attached there is the screenshot of the M 2.3.3 installation. Any idea why these fields are not there?
