cannot access plugin tab after update

Hi,
I’m using this plugin and in the “add plugin” tab, some of my plugins are not available to select for translation (they are disabled as already selected) and also are not available as a tab to do translations.
As I remember, I used to translate them here before some update/upgrade.
I think that My-wp-translate is not showing them as a tab after update/upgrade.
How can I resolve this?
