I got kicked out of my Clan and I am the leader

Hello there, Recently, I was removed from my clan/group, but I was the leader of it. Some of my members got kicked out as well, but some stayed. This is very weird. I tried restarting the league client many times, but it still does not work. I don't want to create a new clan because I am afraid that my leadership will be gone, and the old clan may be disbanded forever. Thank You for your time.
