Removing Mac device completely from Apple Business Essentials

I got in contact with Apple Support and they told me the following about this. When you release a device it is also automatically removed from the Apple Business Essentials and it also has the state "removed" in the database behind the scene. But what they did in the Apple Business Essentials is, they give the users not only the information which device is managed, added etc. but also which device is released/removed. In this case, everything behaves as it should be but with the new "feature" let's say, that you also get removed devices listed.

I tried this, but the device still appears in the list of devices as shown in above screenshot.
