Test
Notice that the harv warnings only show for the 2 sources in this Multiref2 which include an author or last-name.

Notice if you remove the Sfn-style citation from right here → then the harv warnings disappear. Go ahead and try it; edit this page and preview the page to see the difference.

As long as Sfn or any harv-based citation is used anywhere on the page, then the warnings are displayed in error, but only on those citations which use an author or last-name.

Single citations, not bundled in a multiref, display just fine with no warnings, with or without authors.
