When you filter for People Permissions and Entity Role and action of Update, that is for changes of permissions of the roles, so it will show you who changed the permission on the Role. The Member Add or Remove action shows who changed the membership of that role. With the Member Update, you should get any membership change, but I did not see it come up when I made changes. You get to see which user changed membership of which role and who was added or deleted. I don't know why it will sometimes show GUIDs and other times names. It is random at times.
What action were you looking at?
