Custom fields won't save

I left a comment in github (https://github.com/fooplugins/foogallery-custom-attachment-fields/issues/1) but in case you don’t read those, I thought I’d repost here.

I set up some custom attachment fields, but they don’t save when they’re modified. They appear to work when I first add attachments, but thereafter they sporadically and partially save, and no matter what I do I can’t seem to completely clear them.

Thanks in advance for your help!
