You're currently just a member of the group, not the clan. You will have to head to the group's homepage and select [b]Set as active clan[/b] before it will appear in game. https://www.bungie.net/en/Clan/Detail/1290972 If you have already done this and you received a notification that it is pending, this means you need to be approved. Any admins of the group can approve you joining the clan. I would suggest getting in contact with one of them.
