How do I Exit the flashpoint

I am a sith assasin and im playing the flashpoint forged alliance part 1 the attack on tython, but my problem is fater I enter the jedi temple and beat the Jedi master inside and i have to go to the holoterminal but i cant because the forcefield wall does not go away. Before I fight the Jedi master boss I have to click on the panel then i go into a cut sceen and then fight the jedi, but the forcefield is supposed to go away but its still there and I've restarted the flashpoint twice. Can someone help me
