Class Sync Issue: Button Duplication in Webflow Components

Hello, I am having an issue with Class Sync. It is enabled, and I followed the tutorial: https://www.relume.io/resources/docs/how-to-fix-and-prevent-class-duplication-in-webflow?utm_source=chatgpt.com But it still doesn't work. Every time I paste a component, I get button 2. Thank you in advance.
