Classes Missing in Webflow After Relume Import App Use

Issue report. Classes not showing in Webflow after using Relume Site Builder Import App

1.
Cloned the base
2.
Installed the Relume Site Builder Import App
3.
Classes have been added, the styles render in the designer, show in the browser, but they are not showing in the designer style selector input.
4.
Issue: you cannot remove the class from these elements i.e. the whole webflow experience is broken 😩

Reported to Webflow - they have suggested it is an issue with the Relume App but have not offered a fix. Was hoping Team Relume could help here.
