ClusterMoreUpdatesModal component did not get internationalized when the rest of the Administration section did as the result of any oversight on my part.
Checked on 4.7.0-0.nightly-2020-12-21-131655, the fix has been contained in the payload. Just check fix in code since no available 3.7 release version for test now.
