Duplicate files location?

I'm used the find duplicate files feature many times. Once found, I delete depending on where the duplicate is located. But I just ran it tonight and there is no column showing were the duplicates are. I tried resetting folder options, even though all I had changed was turning off autosize. I tried adding "location" to the display. Nothing works. Unless I know were the files are, I don't know what to delete.

What happens when you try doing that?

After upgrading to the latest version I was able to add it. But I also think I was not adding it correctly before. Not sure, but I think I might have been double-clicking on the choice instead of pressing the to move it to the right panel. One thing I do know for sure is I was neglecting to specify a width for the column.

Anyway, I have no idea why that column disappeared in the first place, but it's back now.

Double-clicking should do the same thing and widths are optional so it shouldn't have been either of those, just so you don't worry about them next time you add a column.
