I recently made an update to my main control page.  I've got 28 pushbuttons, 20 3-color pilot lights that I also use as buttons, 24 other 3-color pilot lights as indicators, and another 50 boolean/real/string values the system is grabbing from a couple of PLCs.

We've noticed that for some reason, some of the 3-color pilot lights (on the right side of the page, not sure if that matters - the ones circled with yellow highlight in the attached screenshot) don't change colors when the boolean values in the PLC change.  It will show the correct color when the page is loaded, but just hold that color no matter what the value in the PLC does.  For those particular buttons, when I made the update, I did not change them at all, and they were functioning properly before my update. 

Any ideas why it would be doing that?

What version of AdvancedHMI are you using?

Add a BasicLabel next to one of the PilotLights using the same address for PLCAddressValue in the BasicLabel to see what it shows as the value.
