Troubleshooting an Older Webflow Site with Class Sync Issues

The community member is new to Webflow and is experiencing an issue with an older site where class sync is turned on. Another community member suggests changing the library preferences to prevent components from importing variables that are not present in the project, and provides a link to a resource that explains how to do this. The original poster responds that it's too late, and another community member confirms that the same resource will show how to fix the issue after the fact. The original poster then thanks the community and mentions that the suggested solution worked, though they had to manually disconnect some troubling instances.
