Hi @sns,

You can remove missing feature using PowerShell:

function Remove-SPFeatureFromContentDB($ContentDb, $FeatureId, [switch]$ReportOnly)  
{  
    $db = Get-SPDatabase | where { $_.Name -eq $ContentDb }  
    [bool]$report = $false  
    if ($ReportOnly) { $report = $true }  
      
    $db.Sites | ForEach-Object {  
          
        Remove-SPFeature -obj $_ -objName "site collection" -featId $FeatureId -report $report  
                  
        $_ | Get-SPWeb -Limit all | ForEach-Object {  
              
            Remove-SPFeature -obj $_ -objName "site" -featId $FeatureId -report $report  
        }  
    }  
}  
  
function Remove-SPFeature($obj, $objName, $featId, [bool]$report)  
{  
    $feature = $obj.Features[$featId]  
      
    if ($feature -ne $null) {  
        if ($report) {  
            write-host "Feature found in" $objName ":" $obj.Url -foregroundcolor Red  
        }  
        else  
        {  
            try {  
                $obj.Features.Remove($feature.DefinitionId, $true)  
                write-host "Feature successfully removed from" $objName ":" $obj.Url -foregroundcolor Red  
            }  
            catch {  
                write-host "There has been an error trying to remove the feature:" $_  
            }  
        }  
    }  
    else {  
        write-host "Feature ID specified does not exist in" $objName ":" $obj.Url  
    }  
}  
  
$contentDatabaseName = Read-Host "Enter the Content Datbase name:"  
$featureId = Read-Host "Enter the feature Id :"  
  
Remove-SPFeatureFromContentDB -ContentDB $contentDatabaseName -FeatureId $featureId –ReportOnly
