Different metadata displayed on files of the same type

[Steven P. Ulrick]

Hello Everyone,
I don't THINK I have seen this issue mentioned on this list or on the 
FAQ's/Documentation  that we are frequently pointed to.  If I missed it, I do 
apologize.

First, check out these screenshots:

http://www.afolkey2.net/~steve/NepomukStrigi-Metadata-Screenshot-002.png

You will notice that on NepomukStrigi-Metadata-Screenshot-001.png only the "Is 
part of:" metadata is displayed.

In addition to that field, in the NepomukStrigi-Metadata-Screenshot-002.png 
screenshot you will see the following:

"Album:"
"Average bitrate:"
"Channels:"
"Codec:"
"Comment:"
"Content created:"
"Performer:"
"Sample rate:"
"Title:"
"Track number:"

Any ideas on what may be causing this?  Permissions and ownership are the same 
on all files.
