Many Windows 11 users have reported this issue. However, in every case, the old updates vanished automatically after some time.
Please try clearing the Qmgr cache using PowerShell admin.
Get-Service -Name wuauserv,bits,cryptsvc | Stop-Service
and
Remove-Item -Path "$env:ALLUSERSPROFILE\Application Data\Microsoft\Network\Downloader\qmgr*.dat"
