Delete the other instance, eventually retag this one to common if you prefer.
What is unclear from System Requirements - macOS? And this question makes me assume that the description If you’re a technology enthusiast, early adopter or power user, this version is for you! doesn’t match your user profile. So use 6.4.6 (as of today, but 6.4.7 is in the wings).
