My Playtime stats are incorrect.

I added screenshots of my characters playtime. Displays 42D 6H 0M when it should say 55D 11H 20M

Main Character
2nd Character
3rd Character
4th Character

Agreed, I am seeing this issue also, on my account for all four alts.
Assumed (expected) it to take the greater number (time elapsed) of the four characters.
Perhaps its averaging it out across all of the (alt time expired divided by [x] alts) for some of us?
