PaperCutSoftware.GhostTrap always reinstalls via WinGet – installed version detected as Unknown

[jcook-ccl]

Overview
When upgrading PaperCutSoftware.GhostTrap using WinGet, the package is reinstalled on every run instead of being recognised as up to date.
winget list reports the installed version as Unknown, which appears to cause WinGet to treat the application as not installed or not matching the available version.
Observed output:

winget list --name "Ghost Trap 1.6.10.04"

Name                 Id                         Version Available Source
------------------------------------------------------------------------
Ghost Trap 1.6.10.04 PaperCutSoftware.GhostTrap Unknown 1.6.10.04 winget

Expected behaviour
Installed version should be detected correctly (e.g. 1.6.10.04)
winget upgrade should not reinstall when already up to date

Actual behaviour

Installed version shows as Unknown
winget upgrade reinstalls the package repeatedly

Impact
Causes repeated installations in automated deployments and prevents reliable version tracking.
Suspected cause
Version detection issue (likely missing or incorrect DisplayVersion / installer metadata or manifest mapping).
