WebCORE piston call SHTM not delaying

I have a WebCORE piston that executes properly if I "Test" the piston in WebCORE, but if I execute it via a button in Actiontiles, it doesn't perform as expected. It is regarding a virtual switch that sets the SHTM to "away" mode. I want it to delay 180 seconds. The WebCORE piston is as such:

With virtual switch
Wait 180 Seconds
Set virtual switch to "On"

So when I "test" the piston, it does this. I set up a shortcut in actiontiles to the piston, and put a button on my panel. When I press the button, it doesn't process the line that waits 180 seconds. Pretty stumped as to why. I've confirmed it's pointing to the correct piston.
