Looks like they are missing the Canned Responses feature. My first troubleshooting step when people don't have things it seems like they should have is to check their permissions and/or licenses. In this case, the agents need the Responses > Library > View permission and the Responses > Response > View permission. I believe you need a PureCloud 2 or 3 license for canned responses as well.
