Access to Plugin not working

A specific plugin function (setting appointments) I want to have open to staff to monitor their appointments. I see the name of the plugin on the Restrictions list, clicked it, but don’t see it when I go in as that Role (or User, tried both ways).

What would restrict it not showing “Amelia” which is the plugin I’m trying to give access to?
