Sort domains by traffic

[Tozz]

In Plesk 11.5 (latest) I am unable to sort on 'Traffic' when I click on 'DOmains' as Administrator. The header 'Traffic' is not clickable. Is this my design or is there a bug in the template? It seems strange to me that I can sort on everything but Traffic.

Bumped into this several times.
I just know it has always been that way.
