JSFL Button getting stuck in pressed state

Hi there, I'm building some extensions for Animate via ActionScript calling JSFL functions. I've built quite a few features now, but for the first time encountering a strange issue - when a button is pressed to run a particular JSFL function, it's remaining pressed even after the code has finished executing.

I'm afraid I can't share the code, but just so it's clear you can see the buttons. I'm assuming, for whatever reason, Actionscript is under the impression that the code is still executing? If anyone has come across this before would love to know how you resolved it!

Thanks for any help!
