Ryan is noted to have been born in 1995 and was 12 in the flashback when she was kidnapped in 2007. When the search party comes up looking for Beth it creates an problem as by 2007 Beth had been declared legally dead since Mary's mother faked her death only fourteen months after she was kidnapped on January 26, 2003 (March, 2004). So by using the search party as a time marker, Ryan should have been 8 years old when she was kidnapped by the Candy Lady, not 12. Unless there was an other white girl who had gone missing 4 years after the Kane family's car crash, or the dates were changed or compressed by the Crisis, which melded the histories of Earth-1 and Earth-38.
Also stated by Kate's logs of when and where the search parties where for Beth contradicts Kate's voiceover statement in The Rabbit Hole (2019) that everyone eventually stopped helping the surviving family look for Beth so there's no way that search party from Ryan's memory was still helping them in October of 2003.
Some of the comics in Ryan's flashbacks have the circa-2016 DC Comics logo, nearly a decade too early.
