Windows 10 IoT UWF File Exclusions and Subfolders don't get excluded.

I am running a Windows 10 IoT Enterprise LTSC 2021 device and running the UWF in RAM.
I was led to believe that if you add in any file exclusions of a type folder, then any subfolders beneath it, are also excluded.

This doesn't seem to be the case, I have the following exclusions in place, but every time I run a reboot and and scan the content of the overlay, it seems that content is being written to it, in these very folders and subfolders.

Here are the exclusions and here is some of the overlay content being created, even with these exclusions in place.

Exclusions

Current Session Settings
Current Session Exclusions for Volume b46d2214-7573-4617-8f88-266660f4486a [C:]
    C:\TEMP
    C:\Program Files (x86)\Microsoft\EdgeUpdate
    C:\Program Files (x86)\Microsoft\EdgeCore
    C:\Program Files (x86)\Microsoft\Edge
    C:\Program Files (x86)\Microsoft\Edge\Application
    C:\Program Files\Microsoft Defender
    C:\ProgramData\Microsoft\Windows Defender
    C:\Windows\WindowsUpdate.log
    C:\Windows\Temp\MpCmdRun.log
    C:\Windows\ServiceProfiles\NetworkService\AppData\Local\Microsoft\Windows\DeliveryOptimization\Cache
    C:\Windows\System32\LogFiles
    C:\Windows\System32\winevt\Logs

Yet the overlay shows that content was written to those areas, see below, particularly within the folders shown below.

Am I doing something fundamentally wrong here, or is there a real problem with the Windows 10 UWF?

Thanks in advance.
