Can't Lower Bandwidth on HFSC Traffic shaper, Bug?

[churchtechguy]

I have an HFSC traffic shaper setup on my WAN interface. I'm trying to lower the bandwidth on the parent queue because I'm going to have a slower WAN connection. Running 2.4.5-RELEASE-p1. I have my queues setup like this:

qInternet
->qLowDelay 45%
->qBestEffort 5%
->qBulk 5%
->qVideo 40%

Because its on percentages I don't believe I should ever get this error. I have all percentages only entered in the top box, not in the lower boxes for upper limit, real time or link share on the bottom. I tried re-saving all queues again and applying changes as well as disabling and re-enabling the root queue.

Is this a bug? Its kind of annoying.
