My current character score (shamhatt holy priest US Eldre'Thalas) is 2323. However, on the Realm Ranking tab (filtered to only show holy priests) my score is only 2188. The score reports properly on the Guild Ranking tab. As a result on the Realm Rankings I am #45 instead of tied for 6th as my 'proper' score would place me.
As far as i saw everything works properly for your character on any list.Please make sure that first update character by using the "live" button on "Character" tab. Then you will see fresh info for that character on both "Guild" and "Realm" tabs. If you still think there is any problem please send me a private mail.
