How do I select all of the matching variants that Figma highlights?!

This has driven me BATTY for like two years. When I select a component Figma, correctly, selects the same component in other frames throughout my file. But neither “select all with same variant” or “select all with same component” will actually select the other purple instances highlighted.

What am I doing wrong? How do I select all of the instances Figma has identified?!
