I wanted to do Trials for the first time, so i created a fireteam. But I managed to gather some clan mates and did 2 matches (we were crushed both times). Later, I found out that people had joined the fireteam. I messaged them letting them know about the mixup. But, I can't seem to delete the fireteam. What do I do? Edit: I forgot to add that i closed the fireteam so no one else could join, and i cannot see a way to actully delete it.
