Random players added to clan roster

When opening the clan roster, it is populated with random players from communities that are not in the clan. When the clan roster is closed, and re-opened, it shows the correct members, but immediately begins to fill up again with random players.

Not sure if it is related, but when I first logged in, I got 2 messages in the chat saying that the clan features were unavailable, and another one saying clan features were restored. This did not happen again after I restarted the game.

After I restarted the game, it returned to normal. However, after opening a community roster, and then opening the clan roster, it would be populated with members from that community.

This is happening for me on all servers.
