Issue report: classes not showing in webflow after using relume site builder import app

A community member reports an issue with classes not showing in Webflow after using the Relume Site Builder Import App. They cloned the base, installed the app, and the classes were added, but the styles render in the designer and show in the browser, but do not appear in the designer style selector input. The issue is that the classes cannot be removed from the elements, breaking the Webflow experience. The community member reported the issue to Webflow, who suggested it is an issue with the Relume App but did not offer a fix. They are hoping the community can help resolve the issue.
