Custom Properties wont update?

Hi all,

Ok, I am doing a bunch of templates and using the old school way of using the custom properties, yet no matter what I do I can't seem to get the field to update.

Originally I was using the file name for this field "Detailed Description" and want to change it to one of the other properties and as you can see it won't update.

any insight would be greatly appreciated,

Regards,
