Why can't I see kill times and raid comps for Heroic/Normal in Trial of Valor or The Emerald Nightmare?

Raider.IO launched in late January of 2017, and both of those raids had long-since been released, so we never had the opportunity to track the exact times at which your Heroic/Normal kills would have occurred. We allow Mythic rankings to show for the older content, because we are able to validate the exact timestamps at which those kills occurred.
