Barry also apparently stayed in Flashpoint world for a few months before undoing it which would put him sometime past Dante's death.... who knows?

As for Caitlin, I guess she gained her power because Time Quakes from Barry messing with the timeline gave her the meta-gene. She said in one episode that she tested it after the encounter with Killer Frost and didn't have the potential to become a metahuman, so I guess that changed after Flashpoint ended.
