qBittorrent official forums

I have seen several places where help docs or change logs indicate that I should be able to sort the contents tab in qb.  However, I am not able to get the contents to sort.  I am not sure if this is only affecting the Linux client or all platforms.  I am currently running Ubuntu 12.04 and qBittorrent 2.9.10 obtained through the stable PPA channel for qBittorrent.

Is there a configuration option that I am overlooking?

Clicking on the column headings has no effect (both right and left clicking.)

Right now it's very inconvenient that the sort order is inverted (meaning descending order.)

Sort of the content works on every column with left click.
Win 7 Pro SP1 32-bit.

Thank you  ironcross, for verifying that,

So it may only be when running on Linux?  Can anyone verify if sorting is available/working with Linux (Specifically Ubuntu)?
