The page hands its accumulated weight to a different URL and drops out of the index itself. On a generated site this is nearly always one wrong line in the template, repeated across every page it produced.
The finding reads:
critical canonical-elsewhere a copy of …: the canonical points there, and that page is open in the build — as it should be if this is a variant (a print version, a second address)Check the template: the canonical must point at the page itself. Right now it hands its weight to another page and drops out of the index.
Collapsed when it fires template-wide. If it appears on 90% or more of the pages — or of one language version — of a site with at least 20 pages, it is a property of the template and is reported once, with the count, instead of once per page.
