Microsoft Azure AD Sync service not showing in Services.msc but shows in Get-Service

Question

We've noticed that "Microsoft Azure AD Sync" & "Microsoft Azure AD Connect Agent Updater" services are not showing up in Services.msc but shows up in Get-Service PowerShell command & also in Task Manager >> Services, as "Microsoft Azure AD Sync (ADSync)" & "Microsoft Azure Connect Agent Updater" (AzureADConnectAgentUpdater).

Investigating further, I've noticed that this service is showing up in not just Get-Service command but also in Registry (Computer\HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\ADSync) – just not in Services.msc

We've tried to repair & reinstall Azure AD Connect sync (Microsoft Entra Connect sync - v2.4.129.0), along with checking SFC & DISM command & further clearing any pending updates & restarting server a few times but still the same.

Is there anything further we'd do to see why the service exists on the server/system, yet not showing up in Services.msc?
