BoundingBoxArray : How can I clear outdated ones on Rviz ?

[CCodie]

Hi developers ! Always thank you for your hard work.

I want to draw some bounding boxes on Rviz
and try to use jsk_recognition_msgs::BoundingBoxArray.

But here's some problem that outdated boxes doesn't disappear like this picture.
(Only boxes with a text are valid)

Even though I set dimensions of outdated boxes to zero and publish that topic again, but it doesn't work. I think there's something with interacting Rviz.
(I can clear outdated ones with push 'reset button' in Rviz window)

When I use visualization_msgs::Marker for drawing some shapes,
I can handle this problem with setting the value visualization_msgs::Marker::lifetime.
So that I can see only updated objects on Rviz.

If there's a way, please let me know...! Thanks.
