I believe all team bonuses works just fine.
Something like this? My team here has 5 team bonuses and all are active.
Though on PC, you can't slide to right to see all the bonuses. But it's all there.
Here's on mobile where you can slide to the right to see all the team bonuses that affects the team.
As you can see my Hellcat has same stats, means all bonuses are active. It just doesn't display all bonuses on PC when you check the bonuses tab
