Dead hardcore character level not displaying correctly

While playing with a hardcore character I leveled up and then got killed without leaving the first game I joined. In the lobby and character list it was listed as a level 1 character. I believe it happened on a classic hardcore character, and I replicated with 2 non-classic hardcore characters. I deleted all but the last named “Dru”. Although after this I closed and reopened the game and the character then showed up as the correct level and appeared ghostly in the lobby.
