Windows 8.1 Pro

WLM 2012 16.4.xxxx.xxxx

After a system refresh I had to reinstall all the applications. After reinstalling WLM, I could find all the previous messages in the users' subfolders. However, when I re-imported them into WLM, all of them displayed the wrong recipient, meaning the recipient is the same as the sender. 

That happens on the main pane, under the TO column. Opening the email message I can see the correct recipient on the TO line.

How can I see again the correct recipients on the TO column?
