Different Page templates in Admin and text editor

Hi!
I want to delete unused templates in my Grav project. When I take a look in the Admin I see a lot more Page Templates than I see in my text editor.
Page Templates in Admin
Page Templates in text editor

Where do these other Page Templates come from? Thanks in advance!

Hey, is there anyone who knows how to deal with this issue? Thanks a lot in advance :)

You may be looking only at your theme folder. Each plug-in has templates within its file structure, too.

Yes, that was the issue. Removed the Events plugin. Thanks!
