Search API 7.x-1.20 not updating

Hi,

The module Search API 7.x-1.20 not updating.

The latest version of Search API is 7.x-1.22. I replaced the old files with the files of new version but in Admin still I see the old version written i.e. 7.x-1.20. Therefore my modules is missing two updates.

Please suggest ways to update the module.

Thanks
Pushkar
