Their website has a mechanic that lists all the cases chronologically so new cases bump down the older cases. All the cases have dates of when they were first posted. Someone complained on Facebook that a more recent identification wasn't featured first on the website and that recent identification was an older case so an older identification that was a more recent case for them was bumped up and someone from the project commented that it's a mechanic of the website that they can't change. To illustrate, check their success stories section on the website. Twinsburg John Doe was announced very recently but the Sumter County Does are above him even though they were announced two years ago. The other difference is that Twinsburg John Doe was posted in June 2019 while the Sumter County Does were posted in July 2019. The cases on the very top are from Gwinnett County, Georgia, both very recent postings. The oldest cases seem to be Kings County Jane Doe from California and Apache Junction Jane Doe, both posted on the same day.
