SEO Report shows duplicate title for pages in Multisite setup

[Swennet]

With a multisite setup, some pages like "Home" will always have the same title on both sites causing a "Each page should have a unique title tag." warning in the SEO Reports.

For reference, the second website lives in a "subdirectory" in the url structure:

• example.com
• example.com/nl

This clutters up the SEO Report with false positives, which should probably be ignored.
