Features Installed but not showing in SharePoint

Got a very strange problem with the features. Even though the solution is installed and features are showing in the features folder but the same features are not appearing in the SharePoint UI

Run SharePoint 2010 / 2013 Management Shell from the central admin server and 

run following command

Install-SPFeature -ScanForFeatures 

This will show you any features that are available in the SharePoint Root but have not been installed. 

You can install any missing features using the command :-

Install-SPFeature -AllExistingFeatures
