Did you setup a reset condition?
It should be the tab right next to the trigger condition and you can set it up like this:
Once you have a reset condition, you should be able to test your reset action successfully. If you are still having issues, I would use the "Copy Actions to Reset" button on the "Trigger Actions" tab and test using a 'known-good' action set to make sure there wasn't a typo or something similar in your reset action logic.
