Unkillable sector 2 conquest

In Sector 2 of Galactic Conquest, whether I play the challenge or regular, I cannot beat the first team of Kelleran Beq, Depa Billaba, temple guard, Qui-gon Jinn, and Ayla secura. I get them down to no helth and they will not die! I used my jedi team which stacks damage over time and almost evryone of them had 20 damage over time and still would not die! Same for my inquistors team! Please make this right, I love the game too much for this.
