The issue is that the predicted species list is built by subtracting this year’s top 10 species (default is 10 species, can also choose 20 or 30) from the historic species list. So if C. cheirifolium is the 12th top species for this year and you’re using the default of 10 top species, then the page thinks that it’s unseen for this year. If you make the radius small enough and/or expand to 20 or 30 species, you can get C. cheirifolium to appear in this year’s seen list instead of the predicted list.
Probably the page should expand the definition of “seen this year” beyond the top 10/20/30 species.
