Indeed. Eobard was erased, but that didn't alter any of the changes he made while he existed. Which made absolute no sense. Apparently the in-universe explanation was, the singularity was supposed to consume everything and rewrite the timeline to a world without Eobard's presence, but Barry and Ronnie stopped the singularity and prevented the timeline from being rewritten (or something like that).
