vSphere: Deploy Template grayed out

I wanted to deploy a template via the vSphere client but I was unable to achieve this task because the option was grayed out.  After restarting the vCenter services and the vCenter server I was still unable to deploy a template.

Non of the options where available. So PowerCLI to the rescue:

$templates = Get-Template *
    foreach($item in $templates){
        $template = $item.Name
                
            #Convert Template back to VM
            Set-Template $template -ToVM -RunAsync
            #Convert Template back to template :S
            $vmview = Get-VM $template | Get-View
            $vmview.MarkAsTemplate()
            
    }

After running the script above. I was able to deploy my templates again
