Windows 10 unattend.xml Disk Configuration Problem - windows

Question

I have some troubles with my answer file. The file works exept the "Disk Configuration" part.
The Dialog popups every time even when i set the Value WillShowUI to "Never". I already tried so many examples from the internet, but none of them worked.
What's the Problem with my file? Is there any log file?
