For some reason the custom fields is not showing up in a particular custom post type on the edit screen. It is showing fine for another custom field and custom post combination on this site. I tried already to take it back to a base theme and turned off all non Toolset plugins and it still isn't showing up.
I ended up deleting all the fields which were created. Then I recreated it. Then I had to purge both the page and the database cache and the fields finally showed up. Something had gotten corrupted in the fields I had and that was stopping it from reading anything beyond the old fields I had already.
