Symptoms
The crawl scope of an onpage analysis is set to "this directory only"
directories other than the one specified in the start URL are also crawled.
For example, domain.tld/en/ was specified, but the directory domain.tld/en/ is also crawled
Cause
The page source text of the start URL specified in the onpage analysis contains a canonical link without a closing slash ( / ).
Solution
Change the canonical link so that it contains a trailing slash.
