Issue on Allstar leaderboard

Dear all,

I’ve been facing an issue with my rankings on the logs. As you can see below :

I have a total all Star Points which is different than the total of all the point boss by boss (978 when it should be aroung 1100).

Is there any reason about that ?

Thanks for your appreciated help and time.
