Problem updating Tomcat threshold

I try to update Tomcat response time threshold from default (<1900, >1900, >2000) to my own setting (<3000, >3000, >4000). I have waited for almost 1 hour now (with 10 minutes update interval) but the new settings still haven't been reflected in the monitoring page.

Attached are 3 screen captures. The first one (health-front.jpg) shows the a Critical Health because the response time is 2076 >2000 (old setting). If you see the bottom part, you can see that the actual current value is 1033 ms and the threshold is already Green. Why I can have 2 different numbers for the same monitor (2076 and 1033)?

The second file (rootcause.jpg) show the Root Cause page, which still shows the old settings, and ANOTHER value (919 ms). Now I have 3 different values in my hand.

The third file (threshold.jpg) shows the Threshold Profile details, which already shows the new settings.

Now, what should I do to make the new settings take effect immediately? I will try to stop-start AppManager after this, but I hope I can get a better solution.
