Appearing, disapearing clan

Looking at the Israeli top clan in Clan Wars we have a clan “biton feed 3” at #15, it is a clan that only got 2 members and therefore does not play Clan War and is stuck on 3885 Trophies.
Sometimes the top Israeli Clan War list shows this clan and sometimes not, can you define if it is in or out?

A clan will remain on the leaderboard as long as it has the required war trophies. We get our data from Supercell and if sometimes it doesn’t show then it’s because Supercell doesn’t show them. I can’t define when it is in/out — it should always be in.
