Is there a way to delete items from the "Alerts" settings page?

I installed Komento and uninstalled it, but there's imported alerts in EasySocial (Settings -> Alerts) that have COM_KOMENTO_etc. language strings. I think these were detected when I ran the "discover" option. I don't see an option to delete these without editing the database manually. Is there a way to do this that I'm not seeing, or could you add a method to delete these (the other sections all have ways of deleting items, not sure why this one does not). I can unpublish them, but I'd like to get rid of them.
