Bug in Plugin WordPress 4.2.2

After turning on WP_DEBUG in wp-config.php

https://codex.wordpress.org/WP_DEBUG

I found this plugin gives the following errors:

Notice: wp_deregister_script was called incorrectly. Scripts and styles should not be registered or enqueued until the wp_enqueue_scripts, admin_enqueue_scripts, or login_enqueue_scripts hooks. Please see Debugging”>Debugging”>https://codex.wordpress.org/Debugging_in_WordPress”>Debugging in WordPress for more information.
