Field edit permissions for administrator

[pseudocoder]

I have the following config for an element, and I'm definitely a Confluence system admin, but the field is still not editable in the user profile.

			<element id="initials" defaultForReports="true">
				<localization locale="en_US" title="Initials" />
				<localization locale="de_DE" title="Initialen" />
				<contextAttribute id="initials" />
				<template>$!{initials}</template>
				<access>
					<group name="internal" view="allowed" />
					<administrator view="allowed" edit="allowed" />
				</access>
			</element>

Any idea what I'm doing wrong?

TIA
