Is these emails outdated?

On the buddypress email, I have about 193 emails templates/touch points and some of this emails do not have situations while some were shown to be published on 2016.  I have recently noticed that I got email notifications with shortcodes and I want to know if some of these emails are outdated. I also noticed that some emails repeated themselves and I do not know the one I have to trash, else this might cause some problems. I would be happy if you can guide me on how to handle this situation. See images below for clarification.
