My triggers work one minute and then not the next with nothing changing

I also note that within the triggers where the logic determines if the Correct/Incorrect layer is shown, you then have a Show Correct that overrides the logic on all of the three buttons.

I have edited the file for you. I've labelled buttons and options. This makes it much easier to check your triggers are working on the correct elements. Prior to this, it was difficult to see if the state was being set on the correct element. It was not in several instance. As you will see with the naming convention, it makes it far easier to manage a complex interaction like this.
