As mentioned on the Description page of the plugin, the plugin automatically handles a situation where a plugin included in its list of plugins not in the directory has returned to the directory (or was never there before):
To insure that plugins that have returned to the www.remarpro.com Plugin Directory since the list was last updated are not incorrectly warned about, the plugin rechecks the www.remarpro.com Plugin Directory to confirm any installed plugins that are on the list have not returned to the directory.
So there isn’t any need to remove the plugin from the list at this time, but it will be removed in the next update, as would happen with any plugin that no longer should be included.
