If you add a skill and it isn't working properly you can easily fix it by disabling it and re-enabling it. You can do this by visiting the Alexa app and tapping on the skill. If you then tap on 'Settings.' you can disable the skill. Next, tap the option to enable it again. This fixes most problems, but you may have the skill connected to the wrong household too. Open the skill and ensure that it's connected to the right household. Finally, there may be an issue with the skill itself. This means that you can wait it out or you can remove the skill and find another one that may work better.
