It seems as though there isn't a place to report bugs for Adobe Bridge, so I thought I'd post this here. Please see this Adobe forum thread to see the bug. I can't fully work with Bridge because of it: http://forums.adobe.com/message/37671...
Apparently I have a similar problem.
I need to upload images into an Image Bank System and have to add the names of each image into the Metadata "Description" item so this Image Bank System can read it.
When I input the Description on Photoshop CS5 it works fine, but when I input it into Bridge CS5 it doesn't appear at the same place - even though I can see it at the right place on Photoshop.
In Bridge CS5 and CS5.1, the 'IPTC Extension' section won't be shown out in Metadata Panel.
Not show the 'IPTC Extension' section in Metadata Panel is incomplete in Bridge CS5 and CS5.1.
In Bridge CS5 and CS5.1, you have to use File info dialog or Metadata Template to apply IPTC Extension metadata. And if you applied IPTC Extension metadata through Metadata Template, you have to use File info dialog to check the new metadata values applied.
