WP Smush Pro installs as WP Smush

Hi,

When i install WP Smush Pro form the WPMUDEV dashboard it reports as WP Smush (standard version) and shows option to upgrade at the config screen. When i try to install from the WPMUDEV site it shows that WP Smush Pro version is installed.

Any ideas what might the cause of this

Regards,

Marcellino
