STORE cache corruption

Store apps work fine yet STORE apps troubleshooter reports that "Windows STORE cache may be damaged/corrupted."
Despite the following measures the error is "not fixed."

STORE has been reset (WSRESET).

STORE apps have been reregistered.
(Get-AppXPackage | Foreach {Add-AppxPackage -DisableDevelopmentMode -Register “$($_.InstallLocation)\AppXManifest.xml”}"

STORE cache has been cleared (per Brink's tutorial).

SFC /scannow and DISM /CheckHealth report no problems.

Curiously, disable User Account Control and rerun the troubleshooter and it will prompt that UAC must be enabled. After doing so, the troubleshooter reports that the UAC issue is fixed, and lists no other problems...

Potential issues that were checked
Some security settings are missing or have been changed	Issue not present
Check for missing or corrupt files	Issue not present
Service registration is missing or corrupt	Issue not present
Microsoft account required	Issue not present
Temporary Internet files location has changed	Issue not present

...until the troubleshooter is run again. Then it's back to "cache may be damaged/corrupted. Not fixed."

Bug? Something overlooked? Ignore it?
