Troubleshooting Relume App: Error with Style Guide Import

Hi! I have an issue when trying to use the relume app in webflow: "You need the latest Relume Style Guide to import" I have an existing website that I want to rebuild from scratch but i want to keep the cms so I cannot start with a fresh page. I deleted everything from the project (just standard h1 etc classes left) And tried to copy and paste the styleguide from the clonable but still the same error. Is there any way to solve this?
