Task Report not available for 2nd,3rd, etc. mentioned users

[OroborosNZ]

I'm trying to get a Task Report (or the main menu's Tasks screen) in a Personal Space listing my tasks. It only lists Task List items where I am the first person @mentioned.

If I'm the second, third or later person @mentioned, the Task doesn't appear in my Task Report.

Any clues how to fix this?

Cheers, Dave.
