Am I doing something wrong ?
Thanks for help

Have you previously used a script that modified window titles? The last title it set is probably still being used.
Type > into the file display to open the command field, then paste this in and push return:
Set LISTERTITLE
That should fix the current window.
Window titles set via command or script are saved as part of the Default Lister and Layouts, so you may need to re-save those after resetting the title, otherwise it'll be back how it was next time you open the Default Lister or Layout.
Wow, so fast, and accurate !
I typed this command, and it fixes the issue indeed 
Thanks a lot !
In fact, I used to have a script that changes the tab title, but I disabled it some times ago.
And many thanks for DOpus, it's a pure gem (since Amiga era 
)
