Are you seeing the results on the clock page of any of your changes? If not, maybe you're not looking at the right screen when you are on the tournament page. If you're modifying an included layout, and your tournament isn't configured or hasn't started, you might be seeing a different screen when on the tournament page than you think you are. By default, the TAB key is configured to display the names of the currently used Screen Set and Screen when on the tournament page. The keys 1 through 9 are configured to go directly to the screen by that index (the screen index is listed next to the screen name on the layout tab). These keys (1-9) go to the screen by that index and immediately engage the screen lock, so that the screen doesn't automatically change based on your tournament state.
