Member image not showing in admin

I've created some additional fields in members.html, one of which is an image field

<perch:members type="image" id="charity_logo" label="Charity Logo" width="150" height="150" crop="false" order="2" bucket="Logos" />

Everything is working as expected, except the image does not show up in the admin area. It uploads fine and can be viewed in the asset panel and I can retrieve it on the front end...

$image = perch_member_get('charity_logo'); ?>
<img src="/perch/resources/Logos/<?php echo $image['sizes']['w150h150c0']['path'];  ?>" alt="<?php echo perch_member_get('alt'); ?>" />

Ant idea why it does not show in the admin area?

Thanks
