Clan - Member Missing Overview & Count

since two days now we are missing Clan Members in the Clan Overview and the Count of the Members is incorrect.
The Members are still in the Clan you can see this only if you look into their profil when they are in you friendlist.
When you search for the Clan with the “Clan search” you see also the correct count of Members.
Interesting thing is only Members with beginning “I” or “J” in their Name are missing. Clan problem is on EU Server
