We are aware of a current issue in the UC Surface 2.0.1 release where meter scale markings on the input and output meters are missing.
If you are not affected by any of the issues that were fixed by the 2.0.1 release, and the meter scale markings are needed immediately, the only option would be to revert to the previous/initial UC Surface 2.0 release on Mac and PC until the issue is addressed in the next Universal Control release. We apologize for the inconvenience this may cause.
