Messes up the plugin listings

When plugin ios activated only a few plugins are even listed on wp-admin/plugins.php. They are still there, but not visble any longer.

When I de-activate the plugin all plugins are visible again.

Is the plugin safe to use any longer?

Theme used: Divi 3.0.40.
All other plugins are updated.
This goes for all 40+ sites I installed the plugin.
