Quinn B. yeah so you'll first need to clean all duplicate classes out of the project first before we can even begin to prevent the issue. Once you have cleaned all duplicate classes, we'll want to take a look at some settings.
Here's a doc on that: https://www.relume.io/resources/docs/how-to-fix-and-prevent-class-duplication-in-webflow
We also have a new version of the extension coming out in a few days that will keep the class sync more persistent across projects - so if you are toggling between projects right now there is a chance that the class sync had turned off without you knowing it. But once you clean your project entirely of class duplication, try to paste in a component again and if its still duplicating classes - try the troubleshooting tips at the bottom of that doc. After all of that, if you are still having issues - please reach out so that we can resolve this for you. Its incredibly frustrating to have classes duplicating. Its also an incredibly complex feature with a lot of variables to consider, so it will take time to troubleshoot.
