Need help understanding duplicate icons in app permissions.

When I go into my app permissions on several of them there are 2 icons (one of which has a weird keyhole on it). I can turn off the duplicate and it doesn't seem to effect it at all. I have never seen this before and just checked my husbands app permissions to make sure and it was like I'm used to, only having one icon. So I am wondering what this is and has anyone else seen this. I have attached screenshots from a few different permissions so you can see what I mean. I have a Samsung Galaxy...
