Unable to add new role to existing ACL

[Bryan Cole]

Running into some odd behavior. I'm trying to add some new ACLs, but it does not appear that I can add new roles to existing ACLs. I can add rows upon creating a new ACL, but when I return to an existing one, the line does not appear. Security debug doesn't yield anything. Any thoughts on how to troubleshoot further?

New ACL (with elevated permissions)

Existing ACL (with elevated permissions) 

Notice how "Insert a new row..." does not appear.

UPDATE: I can confirm I am in Global scope, and that I've "Elevated role."

Your answer is just what I needed.  I'm new to ServiceNow and ran across this issue while running through a tutorial.  It was driving me nuts that it wasn't working like the author was showing.  Turns out my scope was set to my instance instead of Global.

Thank you, Tanner4!

that will happen if you are not in the right scope.

make sure you are in the application for your table.

Despite having cleared my cookies before when troubleshooting, it appears forcing Chrome restart was necessary to fix this. Must have been a local problem, not sure why clearing cache/cookies didn't help.
