"properties" cannot be changed.

[W C]

For months I have been able to set the order of listings in “open” alphabetically, date added, etc.

All of a sudden the column headers are for music files such as album, rating. etc. This is totally useless as I am not working with music files.

I went to “properties” and changed the setting to “all documents.” Nothing changed.

What can I do to fix this?

Note that I did NOT make any changes to settings when it changed to music headers.
