Gauge Alerts are not working

Hi,

I am facing one strange problem with Xcelcious, I have Gauges where the alerts colours are based on the ranges, two of the Gaguges Alerts are not working unless the selection data is not refreshed even the default values are selected which is working for few other Gauges ok.But surprisingly for two gauges the alerts are not wroking even the values behind these are getting refreshed properly.

Thanks

Zahid
