CM Power Management Plan - Wake Up Timers not working

[spgsitsupport]

CM Power Plan has an option for desktop computers

when this is applied to collection wakeup timers are disabled! (I can enable them by hand of course - the picture below shows them enabled by hand)

Microsoft Windows [Version 10.0.14393]

C:\WINDOWS\system32>powercfg /list

Existing Power Schemes (* Active)
-----------------------------------
Power Scheme GUID: 36afc83e-6d90-4219-9f8d-622c73bb02f6  (Always On)
Power Scheme GUID: 381b4222-f694-41f0-9685-ff5bb260df2e  (Balanced)
Power Scheme GUID: 8c5e7fda-e8bf-4a96-9a85-a6e23a8c635c  (High performance)
Power Scheme GUID: a1841308-3541-4fab-bc81-f71556f20b4a  (Power saver)
Power Scheme GUID: db310065-829b-4671-9647-2261c00e86ef  (Customized Peak (ConfigMgr)) *

I could play with GPO Registry entries, but easier is to apply script from here

$PowerSchemes = (powercfg.exe /LIST) | Select-String "power scheme guid" -List
$AllowWakeTimersGUID = ((powercfg.exe /q) | Select-String "(Allow wake timers)").tostring().split(" ") | where {($_.length -eq 36) -and ([guid]$_)} 
 
foreach ($PowerScheme in $PowerSchemes) {
   $PowerSchemeGUID = $PowerScheme.tostring().split(" ") | where {($_.length -eq 36) -and ([guid]$_)}
   foreach ($Argument in ("/SETDCVALUEINDEX $PowerSchemeGUID SUB_SLEEP $AllowWakeTimersGUID 1","/SETACVALUEINDEX $PowerSchemeGUID SUB_SLEEP $AllowWakeTimersGUID 1")) {
    Start-Process powercfg.exe -ArgumentList $Argument -Wait -Verb runas -WindowStyle Hidden}}

Not an ideal, as I would expect that Enabled really means Enabled

Anybody else noticed it?
