Hello there @FrancescaV and good to you.
Unfortunately, there's no function to delete F5 inactive members. The only way is to either create a new one and invite active members playing in this Community or exit the team and join an active customised team here.
Or if you're in a random group, and you're put into a team with a player who doesn't keep contributing to your team, the Fantastic Five friend-finder will keep all the active players grouped in the next selection. You may not be in the same team next time, but you'll be sure to pair with active players for the greatest chances of success!
Please let us know if you need help with other issues in the game.
Thank you and good luck ☺️
