Problem while updating usable width for Nokia N95 8GB NAM

Hello,

I've experienced problems while using the device atlas database for Nokia N95 8GB NAM. The one that's named N95_8GB with an underscore.
I noticed it doesn't have a usable width value so I added one.
The problem is it doesn't add it anywhere, not in the database or in "+ My Data" download.

Anyone? :)

Thanks in advance.
