For some reason my experience gained in a week isn't updating is this an occurring bug? It only started happening to me recently.

Graph for experience distribution for this week not showing either, It just shows my experience gained in a day after the daily reset tick it all reverts back to 0.

Is this due to all the frequent name changes? Or because a friend of mine had the name previously before me. I'm not entirely sure. If the profile can be deleted and If I have to re-create it I can do so
