If the tooltip showing the incorrect number of kills, then please check the following:
Your addon may be out of date.
Update your character on the site and make sure its showing correctly there.
Wait for the next addon update to reflect the new information, especially if you just got new kills.
If it does not show your raid kills at all, then please check the following:
You haven't been removed from the addon due to inactivity.
You have killed at least 30% of the raid bosses.
This is 3/10 for Sanctum of Domination on any difficulty but LFR.
Your addon may be out of date.
If all of the above is good and after the next addon up the problem is not resolved, please reach out to us for us to look into your issue.
