Images: Use as field value broken

Hello,

I'm having a bit of trouble with image fields where the 'use as field value' button disappears after using the 'search' or 'filter' functions in the media library twice in a row.

The first search or filter still shows the button, but if you search again or apply a filter it disappears!

Versions:
Wordpress: 3.5.1
wp-types: 1.3.1

Thanks for any help!
